corrasion

1 Weathering prepares the material for transportation and transportation leads to corrasion.

2 Nowhere else on the face of the globe is one so vividly impressed by the vastness of the work of corrasion as in the northwestern part of Arizona.

3 These broad canyons, or canyon valleys, are carved by the streams in obedience to an interesting law of corrasion.

4 The solution effected by the waters of a stream may also be regarded as a part of corrasion.

5 Weathering, wash, and lateral corrasion of the stream continue to widen the valley after it has reached baselevel.

6 Whether the reduction of the hills exceeded the deepening of the valleys, or whether the reverse was true, so far as corrasion alone is concerned, is uncertain.

7 If the land of southern Wisconsin remained low for a time after the uplift which brought the Paleozoic sedimentation to a close, weathering would have exceeded transportation and corrasion.

8 The processes of weathering began as soon as the surface was exposed to the weather, and corrasion by running water began with the first shower which fell upon it.
