Water moving downhill will carry with it any particles that it can move. So moving water wears away - erodes - the ground over which it flows. In the course of time rivers have sculptured out their valleys in this way.
In some areas man's activities have greatly increased the erosive effects of rainfall. Too intensive cultivation southern cultivation of southern areas of the United States in the 1700s broke up the protective cover of vegetation that the settlers found there. Heavy rains, falling on the cleared ground, ripped out rills that quickly widened and deepened into a mosaic of gullies. Strong winds, blowing away the soil, hastened the development of such areas, known as "badlands" [5].
