Plate Tectonics Quotes

“You might think that, by now, people would have become accustomed to the idea of natural catastrophes. We live on a planet that is still cooling and which has fissures and faults in its crust; this much is accepted even by those who think that the globe is only six thousand years old, as well as by those who believe that the earth was "designed" to be this way. Even in such a case, it is to be expected that earthquakes will occur and that, if they occur under the seabed, tidal waves will occur also. Yet two sorts of error are still absolutely commonplace. The first of these is the idiotic belief that seismic events are somehow "timed" to express the will of God. Thus, reasoning back from the effect, people will seriously attempt to guess what sin or which profanity led to the verdict of the tectonic plates. The second error, common even among humanists, is to borrow the same fallacy for satirical purposes and to employ it to disprove a benign deity.”

“Much as I admired the elegance of physical theories, which at that time geology wholly lacked, I preferred a life in the woods to one in the laboratory.”

“Certain English geologists produced confusion by embracing continental drift and then drawing up narratives and maps that showed continents moving all over the earth with respect to a fixed and undriftable England.”

“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.”

“Greenhouse gases, like carbon dioxide, absorb infrared energy and help warm the planet. So they're absolutely crucial. The problem is that their concentration in the atmosphere needs to be regulated as the sun slowly brightens. Otherwise, the Earth would not be able to stabilize its surface temperature, which would be disastrous.

Plate tectonics cycles fragments of the Earth's crust -- including limestone, which is made up of calcium, carbon dioxide, and oxygen atoms -- down into the mantle. There, the planet's internal heat releases the carbon dioxide, which is then continually vented to the atmosphere through volcanoes. It's quite an elaborate process, but the end result is a kind of thermostat that keeps the greenhouse gases in balance and our surface temperature under control.

“Volcanologists have a tendency to drift westward in the United States because that's where the action is tectonically. North and Central America occupy the western portion of a big slab of the earth's crust known as the North American plate, which is shaped roughly like an inverted triangle. The bottom of the triangle is in the middle of the Atlantic Ocean halfway between South America and Africa. The top two corners are north of Siberia and northwest of Greenland. This piece of the earth's crust is constantly jockeying for position with the tectonic plates that surround it. In some places, like Iceland, the North American plate is pulling away from an adjoining plate, and molten material is welling up to fill the gap. In other places, like California, the North American plate is slipping past an adjoining plate, often getting stuck and then breaking free in earthquake-inducing jolts.

But the most dramatic and dangerous of these plate interactions occur in the Pacific Northwest. There, in a line from southern British Columbia to Northern California, a small piece of oceanic crust is being forced under the edge of the North American plate at the rate of a few inches per year.”

“North America and Europe are getting farther apart by 1.5 centimeters per year. Australia is heading for Hawaii at about 7 centimeters per year. The plates on our planet move about as fast as hair grows on our scalps.”
