Geolo(ic Erosion or )natural) erosion, is the action of thewind, water, and gravity in wearing away rock to form soiland shape the ground surface. Except for some stream and

shore erosion, it is a relatively slow, continuous process thatoften goes unnoticed.

Accelerate Erosion is the speeding up of erosion due tohuman activity. Whenever we destroy the natural vegetation

or alter the contour of the ground without providing some sortof surface protection, we greatly increase the rate of erosion.Farming, construction, logging, and mining are the principlecauses of accelerated erosion. These activities radically upsetthe delicate balance that nature has developed betweenrainfall and runo.
