Bones on the left side of the body showed consistent patterns of corrasion, more than on the right side, indicating that this was the side of the body that eroded out of the bank first.    From Wordnik.com.  [Doug Owsley on Kennewick Man] Reference

The powers of erosion are far slower than those of corrasion, especially in an arid region, because they are intermittent.    From Wordnik.com.  [The Romance of the Colorado River] Reference

Where rocks take a polish, as in Marble Canyon, the scouring and polishing work of corrasion is seen in the shining bright surface as far as the water rises.    From Wordnik.com.  [The Romance of the Colorado River] Reference

This backward drainage leaves the immediate brink, or "rim," till the last, in its work of erosion and corrasion, and the rim consequently is left higher than the region away from it.    From Wordnik.com.  [The Romance of the Colorado River] Reference

It is also clear that if, by some chance, the precipitation of the high sources should increase, the corrasion of the stream-beds in the canyons would likewise increase and outrun with still greater ease the erosion of their immediate surroundings.    From Wordnik.com.  [The Romance of the Colorado River] Reference
