"Erosion" Quotes from Famous Books
 ... of the country to the south, for eighty miles unbroken; and then for fifty miles further is now exhibited in outlying areas and detached masses, separated from the main body by the exercise of the power of erosion through prolonged ages. One hundred and thirty miles in length, and perhaps thirty in breadth at its widest, the area of a principality lies swallowed up for ever. From craters existing probably in the San Antonio mountain and in the Ute Peak, near the boundary of Colorado, and possibly ...

... any complete revolution. If, at any time, the sun radiated much less than its present amount of heat, no water could have existed on the earth's surface except in the form of ice; there would have been scarcely any evaporation, and the geological changes due to erosion could not have taken place. Moreover, the commencement of the geological operations of which we speak is by no means the commencement of the earth's existence. The theories of both parties agree that, ...

To this complexion we shall come at last. To be sure, the genius of man will continue to cut channels in the monotonous plain; erosion will relieve the dreary prospect with form and color, but it bids fair to be, for the most part, a flat and dry world, from which many of us will part with a minimum of regret. There will remain the inextinguishable ...

The place is indeed altogether indescribable—surely one of the most striking testimonies to the force of erosion existing on the earth's surface. The explanation of the phenomenon is found here. At a remote period of geological history the action of mighty torrents let loose sculptured these fantastic and grandiose monoliths, bored these arcades and galleries, hollowed ...

... also occur in the articular cartilages. They quickly lose their peculiar glistening polish, their semitransparency is lost, and the natural tint of a pearl-like blue gives way to a dirty yellow. Later this is followed by erosion of the cartilages at such points as they happen to be in greatest contact. The ends of the bones are thus exposed, and their medullary cavities exposed to infection. As a result we get in them the changes we have already described ...

All the waters of the channels north of Wrangell are green or yellowish from glacier erosion. We had a good view of the glaciers all the way to Juneau, but not of their high, cloud-veiled fountains.

Cutting it, here and there, are little canons, like that through which the Colorado rolls, not a mile deep, but still illustrative of the erosion made here by the rivers of a distant age; for these gashes are the result of rushing water, and every stone upon this small plateau has been worn round and smooth by friction with its fellows, tossed, whirled, and beaten by the waves of centuries.

The river, though it has so little power in transporting even inconsiderable fragments, yet in the lapse of ages might produce by its gradual erosion an effect of which it is difficult to judge the amount.

Some of the valleys are of considerable width; in other cases the opposite walls of the gorges are but two or three hundred yards apart, and fall almost vertically thousands of feet, representing an erosion of hard rock of many millions of cubic feet.

In Mexico the same formation must have existed, but the basins have been filled up by material discharged from volcanoes and from the erosion of the mountains themselves, doubtless caused by the severe and sudden rain-storms and rapid changes of temperature characteristic of these regions.

We were by this time far above the junction of the Missouri River with the Mississippi—a point traceable by a long line of discolored water stained with the erosion of the mountains and plains far up the Missouri. As the boat advanced, hour after hour, finally approaching the prairie country beyond the Missouri forests, I found little in the surroundings to ...

The blue sky, seen beyond a gaunt profile of one of the farther summits that defined its craggy serrated edge against the ultimate distances ...

For a bare instant the cave-in had set him free of the pack, and in that space he gave a single leap over ...

Gravels may be the filling up of a valley which was previously eroded; note the highest level at which they can be traced; often little pockets of deposit, or traces of sandy strata, can be found clinging high up on cliffs; also note ...

... Xosa II. There was no living thing in sight. The ground itself was pebbles and small rocks and minor boulders—all apparently tumbled from the starkly magnificent mountains to one side. There were monstrous, many-colored cliffs and mesas, every one eaten at in the unmistakable fashion of wind-erosion. Through a notch in the mountain wall before them a strange, fan-shaped, frozen formation appeared. If such a thing had been credible, Bordman would have said that it was a flow of sand simulating a waterfall. And everywhere ...

If the involvement persists with sufficient active inflammation, there may follow erosion of cartilage and incurable lameness. If extensive necrosis of cartilage takes place, the attendant pain will be sufficient to cause the animal to favor the diseased part and such immobilization enhances early ankylosis—nature's substitute for resolution ...

The masses presented all the appearance and detail of erosion shown by the great mountain mass of the country itself; looking at one of these little models, only a few feet across, and then gazing out upon the great tangle of mountain peaks around us, one could almost imagine that the one was the intentional reproduction of the other, in miniature. ...
