Erosion

Explanation:

Erosion is the washing away of the top layer of the earth crust by natural forces or through human activities.

Erosion occurs today through activities of wind, water, glacier and human induced factors. Erosion generally wears away layers of the earth taking them else where. This would generally render the land not useful and not viable to support the ecosystem.

Desertification is one of such process that makes fertile land barren. This can be through removal of trees and some other causes. The land becomes bare and exposed which allows for erosion to become effective.

Urbanization is one other cause of erosion. The mass movement of humans to urban centres has increased the pressure on land. This pressure is evident in the land use pattern we see today. Natural habitats that keeps the ecosystem in check have today become residential areas and industrial parks. These construction activities leaves the land bare and easily eroded.

Deforestation is the removal of forests in a particular forested area. Forests acts as land covers. When these covers are removed, the land becomes exposed and left bare for erosion.
