Erosion and its causes

Good day steemians and welcome to my blog. As a soil scientist, I was wondering on what to write as a newbie and wrote on erosion.

Erosion is the removal or the washing away of the topmost layer of the earth surface which is the soil by the action of running water, waves, glacier and wind. Erosion brings about deformation to land shape.
AGENT OF EROSION

1. Weathering: this is the breaking down of rocks which bring abut changes in the surface layer. In dry climate, the outermost layer of the rock may expand from the heat of the sun and crack off.

2. Water erosion: Water is one of the major agent of erosion experience in Africa, it do not only deform the surface area of the soil but also washed away the soil nutrients which mostly result to soil salinity.

3. Wind Erosion: Wind is one of the agent of soil erosion that normally take place in arid area. Wind blowing on land packs the fine particles of sand and and silt.
   Antropogenics impact on Erosion
   Human activities contribute immensely to soil erosion without which the rate of erosion would have been minimal. Man Cut down trees which serve as windbreaks and their network of roots which helps to hold the soil firm against the action of both rain and wind.
   Housing, industrial development and highway construction which partially or completely destroy the protective canopy of vegetation and increases erosion of certain kinds of soil. Also Overgrazing of Animal bring about desertification which can likewise enhance the rate of erosion. Control measures planting of cover crops and afforestation can help in controling the rate of erosion.

It is high time we remember that the soil is very important and most be managed judiciously. A country who destroys her soil destroys herself.
