where is erosion most likely to occur
As the wind speed decreases, deposition of soil particles begins. Wind erosion most commonly occurs in arid and semi-arid regions, because of the frequent occurrence of dry and windy conditions. This video clip explains the three steps in wind erosion (detachment, transport, and deposition).
Channel erosion can occur on steep land or on land that slopes more gently. Because there are always irregularities in a field, water finds hollows in which to settle and low-lying channels through which to run. As the soil from these channels is washed away, channels or miniature dongas are formed in the field.
Soil erosion occurs when soil is removed through the action of wind and water at a greater rate than it is formed. The soil covering the surface of the earth has taken millions of years to form and we must learn to respect it. Soil is formed at a rate of only 1 cm every 100 to 400 years and it takes 3 000 to 12 000 years to build enough soil to form productive land.
