The decline of geography in academia is easy to understand: we live in an age of ever-increasing specialization, and geography is a generalist's discipline. Imagine the poor geographer trying to explain to someone at a campus cocktail party (or even to an unsympathetic adminitrator) exactly what it is he or she studies. "Geography is Greek for 'writing about the earth.' We study the Earth." "Right, like geologists." "Well, yes, but we're interested in the whole world, not just the rocky bits. Geographers also study oceans, lakes, the water cycle..." "So, it's like oceanography or hydrology." "And the atmosphere." "Meteorology, climatology..." "It's broader than just physical geography. We're also interested in how humans relate to their planet." "How is that different from ecology or environmental science?" "Well, it encompasses them. Aspects of them. But we also study the social and economic and cultural and geopolitical sides of--" "Sociology, economics, cultural studies, poli sci." "Some geographers specialize in different world regions." "Ah, right, we have Asian and African and Latin American studies programs here. But I didn't know they were part of the geography department." "They're not." (Long pause.) "So, uh, what is it that do study then?

Science has nothing in common with religion. Facts and miracles never did, and never will agree. They are not in the least related. They are deadly foes. What has religion to do with facts? Nothing. Can there be Methodist mathematics, Catholic astronomy, Presbyterian geology, Baptist biology, or Episcopal botany?

The new dam, of course, will improve things. If ever filled it will back water to within sight of the Bridge, transforming what was formerly an adventure into a routine motorboat excursion. Those who see it then will not understand that half the beauty of Rainbow Bridge lay in its remoteness, its relative difficulty of access, and in the wilderness surrounding it, of which it was an integral part. When these aspects are removed the Bridge will be no more than an isolated geological oddity, an extension of that museumlike diorama to which industrial tourism tends to reduce the natural world.

In geology the effects to be explained have almost all occurred already, whereas in these other sciences effects actually taking place have to be explained.
James Croll (Climate and Time in Their Geological Relations; A Theory of Secular Changes of the Earth's Climate)
In the same way we find much of the universe, as science discovers it, difficult to understand. Einstein's relativity, quantum uncertainty, black holes, the big bang, the expanding universe, the vast slow movement of geological time – all these are hard to grasp. No wonder science frightens some people. But science can even explain why these things are hard to understand, and why the effort frightens us. We are jumped-up apes, and our brains were only designed to understand the mundane details of how to survive in the stone-age African savannah.
Richard Dawkins (A Devil's Chaplain)
Along with osmium and platinum, iridium is one of the three heaviest (densest) elements on the Table—two cubic feet of it weighs as much as a Buick, which makes iridium one of the world’s best paperweights, able to defy all known office fans. Iridium is also the world’s most famous smoking gun. A thin layer of it can be found worldwide at the famous Cretaceous-Paleogene (K-Pg) boundary† in geological strata, dating from sixty-five million years ago. Not so coincidentally, that’s when every land species larger than a carry-on suitcase went extinct, including the legendary dinosaurs. Iridium is rare on Earth’s surface but relatively common in six-mile metallic asteroids, which, upon colliding with Earth, vaporize on impact, scattering their atoms across Earth’s surface. So, whatever might have been your favorite theory for offing the dinosaurs, a killer asteroid the size of Mount Everest from outer space should be at the top of your list.
Neil deGrasse Tyson (Astrophysics for People in a Hurry (Astrophysics for People in a Hurry Series))
To use the symbolic language of Bodkin’s scheme, he would then be abandoning the conventional estimates of time in relation to his own physical needs, and entering the world of total neuronic time, where the massive intervals of the geological timescale calibrated his existence. Here, a million years was the shortest working unit, and the problems of food and clothing were as irrelevant as they would have been to a Buddhist contemplative lotus-squatting before an empty rice bowl under the protective canopy of the million-headed cobra of eternity.
J.G. Ballard (The Drowned World)
The fascination of any search after truth lies not in the attainment, which at best is found to be very relative, but in the pursuit, where all the powers of the mind and character are brought into play and are absorbed by the task. One feels oneself in contact with something that is infinite and one finds joy that is beyond expression in sounding the abyss of science and the secrets of the infinite mind.
Florence Bascom
And if Francoise then, inspired like a poet with a flood of confused reflections upon bereavement, grief, and family memories, were to plead her inability to rebut my theories, saying: "I don't know how to espress (sic) myself" - I would triumph over her with an ironical and brutal common sense worthy of Dr. Percepied; and if she went on: "All the same she was a geological (sic) relation; there is always the respect due to your geology (sic)," I would shrug my shoulders and say: "It is really very good of me to discuss the matter with an illiterate old woman who cannot speak her own language," adopting, to deliver judgment on Francoise, the mean and narrow outlook of the pedant, whom those who are most contemptuous of him in the impartiality of their own minds are only too prone to copy when they are obliged to play a part upon the vulgar stage of life.
Marcel Proust (Swann’s Way (In Search of Lost Time, #1))
That the geological record is imperfect all will admit; but that it is imperfect to the degree which I require, few will be inclined to admit. If we look to long enough intervals of time, geology plainly declares that all species have changed; and they have changed in the manner which my theory requires, for they have changed slowly and in a graduated manner. We clearly see this in the fossil remains from consecutive formations invariably being much more closely related to each other, than are the fossils from formations distant from each other in time.
Charles Darwin (The Origin of Species)
by knowledge the privilege to BE! His insight refines him. The beauty of nature shines in his own breast. Man is greater that he can see this, and the universe less, because Time and Space relations vanish as laws are known. Here again we are impressed and even daunted by the immense Universe to be explored. "What we know, is a point to what we do not know." Open any recent journal of science, and weigh the problems suggested concerning Light, Heat, Electricity, Magnetism, Physiology, Geology, and judge whether the interest of natural science is likely to be soon exhausted. Passing by many particulars of the discipline of nature, we must not omit to specify two. The exercise of the Will or the
Ralph Waldo Emerson (Nature)
Years ago, I asked an acquaintance who was completing his PhD in geology if he had seen any geological evidence for Noah’s Flood. He answered that he had not. And added that geologists don’t see a “flood layer” like they do the iridium layer all over the world. Since then, after much study and reflection, I have come to the conclusion that if the descriptions of the Flood in the scriptures and related sources are reasonably accurate, geologists have been ignoring what is right before their eyes. No surface feature on Earth would have escaped significant alteration, and in many places the changes would have been extreme! There would be no “flood layer,” but there would be many diverse strata and features providing clues.
David Barker (Science and Religion: Reconciling the Conflicts)
In using the present in order to reveal the past, we assume that the forces in the world are essentially the same through all time; for these forces are based on the very nature of matter, and could not have changed. The ocean has always had its waves, and those waves have always acted in the same manner. Running water on the land has ever had the same power of wear and transportation and mathematical value to its force. The laws of chemistry, heat, electricity, and mechanics have been the same through time. The plan of living structures has been fundamentally one, for the whole series belongs to one system, as much almost as the parts of an animal to the one body; and the relations of life to light and heat, and to the atmosphere, have ever been the same as now.
James Dwight Dana (Manual Of Geology)
The racial categorization of Blackness shares its natality with mining the New World, as does the material impetus for colonialism in the first instance. This means that the idea of Blackness and the displacement and eradication of indigenous peoples get caught and defined in the ontological wake of geology. The human and its subcategory, the inhuman, are historically relational to a discourse of settler-colonial rights and the material practices of extraction, which is to say that the categorization of matter is a spatial execution, of place, land, and person cut from relation through geographic displacement (and relocation through forced settlement and transatlantic slavery). That is, racialization belongs to a material categorization of the division of matter (corporeal and mineralogical) into active and inert. Extractable matter must be both passive (awaiting extraction and possessing of properties) and able to be activated through the mastery of white men.
Kathryn Yusoff (A Billion Black Anthropocenes or None)
Each scenario is about fifteen million years into the future, and each assumes that the Pacific Plate will continue to move northwest at about 2.0 inches per year relative to the interior of North America. In scenario 1, the San Andreas fault is the sole locus of motion. Baja California and coastal California shear away from the rest of the continent to form a long, skinny island. A short ferry ride across the San Andreas Strait connects LA to San Francisco. In scenario 2, all of California west of the Sierra Nevada, together with Baja California, shears away to the northwest. The Gulf of California becomes the Reno Sea, which divides California from Nevada. The scene is reminiscent of how the Arabian Peninsula split from Africa to open the Red Sea some 5 million years ago. In scenario 3, central Nevada splits open through the middle of the Basin and Range province. The widening Gulf of Nevada divides the continent form a large island composed of Washington, Oregon, California, Baja California, and western Nevada. The scene is akin to Madagascar’s origin when it split form eastern Africa to open the Mozambique Channel.
Keith Meldahl
Half a century ago Ostwald (1910) distinguished classicists and romanticists among the scientific investigators: the former being inclined to design schemes and to use consistently the deductions from working hypotheses; the latter being more fit for intuitive discoveries of functional relations between phenomena and therefore more able to open up new fields of study. Examples of both character types are Werner and Hutton. Werner was a real classicist. At the end of the eighteenth century he postulated the theory of “neptunism,” according to which all rocks including granites, were deposited in primeval seas. It was an artificial scheme, but, as a classification system, it worked quite satisfactorily at the time. Hutton, his contemporary and opponent, was more a romanticist. His concept of 'plutonism' supposed continually recurrent circuits of matter, which like gigantic paddle wheels raise material from various depths of the earth and carry it off again. This is a very flexible system which opens the mind to accept the possible occurrence in the course of time of a great variety of interrelated plutonic and tectonic processes.

I still have no choice but to bring out Minerva instead.” “But Minerva doesn’t care about men,” young Charlotte said helpfully. “She prefers dirt and rocks.” “It’s called geology,” Minerva said. “It’s a science.” “It’s certain spinsterhood, is what it is! Unnatural girl. Do sit straight in your chair, at least.” Mrs. Highwood sighed and fanned harder. To Susanna, she said, “I despair of her, truly. This is why Diana must get well, you see. Can you imagine Minerva in Society?” Susanna bit back a smile, all too easily imagining the scene. It would probably resemble her own debut. Like Minerva, she had been absorbed in unladylike pursuits, and the object of her female relations’ oft-voiced despair. At balls, she’d been that freckled Amazon in the corner, who would have been all too happy to blend into the wallpaper, if only her hair color would have allowed it. As for the gentlemen she’d met…not a one of them had managed to sweep her off her feet. To be fair, none of them had tried very hard. She shrugged off the awkward memories. That time was behind her now. Mrs. Highwood’s gaze fell on a book at the corner of the table. “I am gratified to see you keep Mrs. Worthington close at hand.” “Oh yes,” Susanna replied, reaching for the blue, leatherbound tome. “You’ll find copies of Mrs. Worthington’s Wisdom scattered everywhere throughout the village. We find it a very useful book.” “Hear that, Minerva? You would do well to learn it by heart.” When Minerva rolled her eyes, Mrs. Highwood said, “Charlotte, open it now. Read aloud the beginning of Chapter Twelve.” Charlotte reached for the book and opened it, then cleared her throat and read aloud in a dramatic voice. “’Chapter Twelve. The perils of excessive education. A young lady’s intellect should be in all ways like her undergarments. Present, pristine, and imperceptible to the casual observer.’” Mrs. Highwood harrumphed. “Yes. Just so. Hear and believe it, Minerva. Hear and believe every word. As Miss Finch says, you will find that book very useful.” Susanna took a leisurely sip of tea, swallowing with it a bitter lump of indignation. She wasn’t an angry or resentful person, as a matter of course. But once provoked, her passions required formidable effort to conceal. That book provoked her, no end. Mrs. Worthington’s Wisdom for Young Ladies was the bane of sensible girls the world over, crammed with insipid, damaging advice on every page. Susanna could have gleefully crushed its pages to powder with a mortar and pestle, labeled the vial with a skull and crossbones, and placed it on the highest shelf in her stillroom, right beside the dried foxglove leaves and deadly nightshade berries. Instead, she’d made it her mission to remove as many copies as possible from circulation. A sort of quarantine. Former residents of the Queen’s Ruby sent the books from all corners of England. One couldn’t enter a room in Spindle Cove without finding a copy or three of Mrs. Worthington’s Wisdom. And just as Susanna had told Mrs. Highwood, they found the book very useful indeed. It was the perfect size for propping a window open. It also made an excellent doorstop or paperweight. Susanna used her personal copies for pressing herbs. Or occasionally, for target practice. She motioned to Charlotte. “May I?” Taking the volume from the girl’s grip, she raised the book high. Then, with a brisk thwack, she used it to crush a bothersome gnat. With a calm smile, she placed the book on a side table. “Very useful indeed.
Tessa Dare (A Night to Surrender (Spindle Cove, #1))
Through the spectacles of geology, terra firms becomes terra mobilis, and we are forced to reconsider our beliefs of what is solid and what is not. Although we attribute to stone great power to hold back time, to refuse its claims (cairns, stone tablets, monuments, statuary), this is true only in relation to our own mutability. Looked at in the context of the bigger geological picture, rock is as vulnerable to change as any other substance. Above all, geology makes explicit challenges to our understanding of time. It giddies the sense of here-and-now. The imaginative experience of what the writer John McPhee memorably called 'deep time' - the sense of time whose units are not days, hours, minutes or seconds but millions of years or tens of millions of years - crushes the human instant; flattens it to a wafer. Contemplating the immensities of deep time, you face, in a way that is both exquisite and horrifying, the total collapse of your present, compacted to nothingness by the pressures of pasts and futures too extensive to envisage. And it is a physical as well as a cerebral horror, for to acknowledge that the hard rock of a mountain is vulnerable to the attrition of time is of necessity to reflect on the appalling transience of the human body.

Not only the iron on Earth, but also the iron in the entire Solar System, comes from outer space, since the temperature in the Sun is inadequate for the formation of iron. The Sun has a surface temperature of 6,000 degrees Celsius (11,000oF), and a core temperature of approximately 20 million degrees (36 million degrees Fahrenheit). Iron can only be produced in much larger stars than the Sun, where the temperature reaches a few hundred million degrees. When the amount of iron exceeds a certain level in a star, the star can no longer accommodate it, and it eventually explodes in what is called a "nova" or a "supernova." These explosions make it possible for iron to be given off into space.40 One scientific source provides the following information on this subject: There is also evidence for older supernova events: Enhanced levels of iron-60 in deep-sea sediments have been interpreted as indications that a supernova explosion occurred within 90 light-years of the sun about 5 million years ago. Iron-60 is a radioactive isotope of iron, formed in Allah's Miracles in the Qur'an 85 supernova explosions, which decays with a half life of 1.5 million years. An enhanced presence of this isotope in a geologic layer indicates the recent nucleosynthesis of elements nearby in space and their subsequent transport to the earth (perhaps as part of dust grains).41 All this shows that iron did not form on the Earth, but was carried from supernovas, and was "sent down," as stated in the verse. It is clear that this fact could not have been known in the 7th century, when the Qur'an was revealed. Nevertheless, this fact is related in the Qur'an, the word of Allah, Who encompasses all things in His infinite knowledge.

A former Red Guard relates, “I believe many little girls and boys of my generation dreamed of being a geological prospector… Propaganda for recruiting young people to work in this area was very effective.

In the North American Review, in August 1889, in an article titled “The Lesson of Conemaugh,” the director of the U. S. Geological Survey, Major John Wesley Powell, wrote that the dam had not been “properly related to the natural conditions” and concluded: “Modern industries are handling the forces of nature on a stupendous scale. . . .

Archivist / Circuit Bender For the figure of the artist, technical media has meant nods both toward engineering and the archive, as Huhtamo has noted: “the role of the artist-engineer, which rose into prominence in the 1960s (although its two sides rarely met in one person), has at least partly been supplanted by that of the artist-archaeologist.”23 Yet methodologies of reuse, hardware hacking, and circuit bending are becoming increasingly central in this context as well. Bending or repurposing the archive of media history strongly relates to the pioneering works of artists such as Paul DeMarinis, Zoe Beloff, or Gebhard Sengmüller—where a variety of old media technologies have been modified and repurposed to create pseudo-historical objects from a speculative future.

Climates were relatively warm during the geological period referred to as the Cretaceous, which lasted from about 145 to about 66 million years BP. Warm conditions persisted to about 5 million years BP. The forest-tundra boundary extended at that time to latitudes as high as 82° N, some 2,500 km north of its present location, occupying regions of Greenland now permanently covered in ice. There were times when frost-tolerant vegetation was common in Spitsbergen (paleolatitude 79° N), when alligators and flying lemurs lived happily on Ellesmere Island (paleolatitude 78° N), and when palm trees, incapable of surviving even temporary frost conditions, could grow and survive in Central Asia.
Michael B. McElroy (Energy and Climate: Vision for the Future)
Instead of more consumerism – the buying of experiences, the accumulation of things, of eating the ‘other’ – perhaps writers should name their own environment. What is the shape of your watershed? How is your electricity produced? Where is your water treated? Where is your food produced and by whom and how does it travel to your local market? What are the names of the rocks under your feet and around you? What formed those geological features? Who were the first humans here? What flora and fauna live upon it and what are their habits and interfaces? What stars whirl above you and what names have they been given, what lore? How can one trace the relations, find the slippages between histories, the linkages, to find the complexities in naming and of the named? Travel as one’s carbon footprint; travel as a footstep, travel as a naming in a landscape in all its complexity. Homing as a way to place oneself in a constellation of process and being.

My feelings are important for many things. They are essential and valuable. They keep me aware of much that is true and real. But they tell me next to nothing about God or my relation to God. My security comes from who God is, not from how I feel. Discipleship is a decision to live by what I know about God, not by what I feel about him or myself or my neighbors. “As the mountains are round about Jerusalem, so the LORD is round about his people.” The image that announces the dependable, unchanging, safe, secure existence of God’s people comes from geology, not psychology.

I think our maps contributed to a revolution in geological thinking, which is some ways compares to the Copernican revolution. Scientists and the general public got their first relatively realistic image of a vast part of the planet that they could never see. The maps received wide coverage and were widely circulated. They brought the theory of continental drift within the realm of rational speculation. You could see the worldwide mid-ocean ridge and you could see that it coincided with earthquakes. The borders of the plates took shape, leading rapidly to the more comprehensive theory of plate tectonics.

The real underland of language is not the roots of single words, but rather the soil of grammar and syntax, where habits of speech and therefore also habits of thought settle and interact over long periods of time. Grammar and syntax exert powerful influence on the proceedings of language and its users. They shape the ways we relate to each other and to the living world. Words are word-makers – and language is one of the great geological forces of the Anthropocene.

Bone beds turn up sporadically elsewhere, with spectacular examples in the Dinosaur National Monument in the USA and in Mongolia’s Gobi desert. In eastern England there are several within the early Cretaceous strata, which include, as well as bones, structures termed coprolites, some of which represent the petrified faeces of dinosaurs or marine reptiles. In the middle of the 19th century, when England’s population was booming and the farmers were struggling to feed everybody, it was discovered that these fragments (which, being bone, are phosphate-rich) made a superb fertilizer when crushed and acid-treated. A thriving and highly profitable industry formed to quarry away these ‘coprolite beds’. Some considerable figures were involved in this industry. John Henslow, Charles Darwin’s beloved mentor of his time at Cambridge, seems to have first encouraged the farmers of eastern England to use such fossil manure. William Buckland also became involved. An extraordinary combination of early savant of geology at Oxford and Dean of Westminster, he was the first to scientifically describe a dinosaur ( Megalosaurus); carried out his fieldwork in academic gown; reputedly ate his way through the entire animal kingdom; and coined the term ‘coprolite’, using these petrified droppings to help reconstruct the ecology of ancient animals. Later, he energetically collaborated with the celebrated German chemist Justus Liebig (who had worked out how to chemically treat these fossil phosphates to make fertilizer) to show how they could be used by agriculturalists, once demonstrating their efficacy by exhibiting, in Oxford’s Ashmolean Museum, a turnip, a yard in circumference, that he had grown with such prehistoric assistance. It is related strata (geologically rare phosphate-rich deposits, usually biologically formed) that are still a mainstay—if a rapidly depleting one—of modern agriculture. In a very real sense, these particular rocks are keeping us all alive.
Jan Zalasiewicz (Rocks: A Very Short Introduction (Very Short Introductions))
For many geologists, the most important consequence of the recognition of plate tectonics was that it brought confirmation of continental drift. As important, plate tectonics allowed continental drift to be determined with considerable precision. This became immediately clear to Clark Burchfiel, now at Massachusetts Institute of Technology (MIT), who in 1968 had carried out fieldwork in Yugoslavia, and returned home to discover Le Pichon’s paper. By knowing the relative motions between Africa and North America and between Europe and North America, Le Pichon had predicted the motion between Africa and Europe for the previous 80 million years, a history that included not only the present-day convergence between Africa and Europe, but also periods when these two regions moved in different directions relative to one another, including a period when they diverged from one another. This history of relative plate motion wrote a complex history on the rock record of the region affected by the relative movement of Africa and Europe. Nevertheless, Burchfiel had inferred from the geologic history of this rock the times of major changes and had inferred what tectonic processes (convergence, divergence, and directions of relative movement) might be occurring at these times. Le Pichon’s calculated plate motions, from data solely in the Atlantic Ocean, predicted many of Burchfiel’s observations and inferences. A new idea becomes believable when it predicts something that has not yet been measured or explained, especially when the idea is really trying to explain other facts.

Areas that are densely populated today, Chicago, New York, Manchester, Amsterdam, Hamburg, Berlin, Moscow -- in fact most of North America and northern Europe -- were absolutely uninhabitable due to the fact that they were covered by ice-caps several kilometers thick. Conversely, many areas that are uninhabitable today -- on account of being on the bottom of the sea, or in the middle of hostile deserts such as the Sahara (which bloomed for about 4000 years at the end of the last Ice Age) -- were once (and relatively recently) desirable places to live that were capable of supporting dense populations. Geologists calculate that nearly 5 per cent of the earth's surface -- an area of around 25 million square kilometers or 10 million square miles -- has been swallowed by rising sea-levels since the end of the Ice Age. That is roughly the equivalent to the combined areas of the United States and the whole of South America. It is an area almost three times as large as Canada and much larger than China and Europe combined. What adds greatly to the significance of these lost lands of the last Ice Age is not only their enormous area but also -- because they were coastal and in predominantly warm latitudes -- that they would have been among the very best lands available to humanity anywhere in the world at that time. Moreover, although they represent 5 per cent of the earth's surface today, it is worth reminding ourselves that humanity during the Ice Age was denied useful access to much of northern Europe and North America because of the ice-sheets. So the 25 million square kilometers that were lost to the rising seas add up to a great deal more than 5 per cent of the earth's useful and habitable landspace at that time.
Graham Hancock (Underworld: The Mysterious Origins of Civilization)
In the early 1900s a Serbian scientist named Milutin Milanković studied the Earth’s position relative to other planets and came up with the theory of ice ages that we now know is accurate: The gravitational pull of the sun and moon gently affect the Earth’s motion and tilt toward the sun. During parts of this cycle—which can last tens of thousands of years—each of the Earth’s hemispheres gets a little more, or a little less, solar radiation than they’re used to. And that is where the fun begins. Milanković’s theory initially assumed that a tilt of the Earth’s hemispheres caused ravenous winters cold enough to turn the planet into ice. But a Russian meteorologist named Wladimir Köppen dug deeper into Milanković’s work and discovered a fascinating nuance. Moderately cool summers, not cold winters, were the icy culprit. It begins when a summer never gets warm enough to melt the previous winter’s snow. The leftover ice base makes it easier for snow to accumulate the following winter, which increases the odds of snow sticking around in the following summer, which attracts even more accumulation the following winter. Perpetual snow reflects more of the sun’s rays, which exacerbates cooling, which brings more snowfall, and on and on. Within a few hundred years a seasonal snowpack grows into a continental ice sheet, and you’re off to the races. The same thing happens in reverse. An orbital tilt letting more sunlight in melts more of the winter snowpack, which reflects less light the following years, which increases temperatures, which prevents more snow the next year, and so on. That’s the cycle. The amazing thing here is how big something can grow from a relatively small change in conditions. You start with a thin layer of snow left over from a cool summer that no one would think anything of and then, in a geological blink of an eye, the entire Earth is covered in miles-thick ice.

Meteorology . . . is quite as “scientific” as geology and far more so than archaeology—it actually makes more use of scientific instruments, computers, and higher mathematics. . . . Yet we laugh at the weatherman every other day; we are not overawed by his impressive paraphernalia, because we can check up on him any time we feel like it: he makes his learned pronouncements—and then it rains or it doesn’t rain. No scientific conclusion is to be trusted without testing—to the extent to which exact sciences are exact they are also experimental sciences; it is in the laboratory that the oracle must be consulted. But the archaeologist is denied access to the oracle. For him there is no neat and definitive demonstration; he is doomed to plod along, everlastingly protesting and fumbling through a laborious, often rancorous running debate that never ends.
