Natural Erosion

 

Erosion is a natural process which over millions of years can level mountain ranges.

 New soils can be formed through the slow weathering of the parent rock material, and from the deposition of air-borne or water-borne sediments. Under normal climate conditions, and with natural ground cover, soil erosion can often balance out with the rate of soil production. This is called natural, or geological erosion. Also, new soils can become very deep given sufficient time with protective plant cover, and soil formation in these cases greatly exceeds the natural erosion. Unfortunately, these geologic processes are very slow and are often overshadowed by the activities of man.
