Dec 5, 2019 What is soil erosion? Soil erosion, the most common type of land degradation, is a natural process that displaces the upper layer of soil, which is

Although erosion is a natural process, abusive land-use practices such as deforestation and overgrazing can expedite erosion and strip the land of soils needed for food to grow. Erosion is the wearing away of the earth’s surface by the action of natural forces, for example, water, wind and glacial ice. The loose and dissolved materials move from one location to another. Erosion should not be confused with weathering. Erosion is when the top soil is swept away by natural or man-made forces.

The agricultural plants that often replace the trees cannot hold onto the soil and many of these plants, such as coffee, cotton, palm oil, soybean and wheat, can actually worsen soil erosion. Once these sediments are separated from the rocks, erosion is the process that moves the sediments. Erosion is the next chapter’s topic. The four forces of erosion are water, wind, glaciers, and gravity. Water is responsible for most erosion. Water can move most sizes of sediments, depending on the strength of the force. Tunnel erosion is the most severe form of water erosion caused by rainfall or melting snow.

Most nitrogen is simply wasted through denitrification, leaking, erosion and volatilization of ammonia.[i] According to David Montgomery,

In this view, soil erosion has severely threatened the productivity of fertile cropping areas as they are continually degraded. Erosion by Glaciers. Section 1 Daily Dose of Destruction. Glaciers are large masses of moving ice and snow. Don't confuse them with icebergs. Icebergs were once part of glaciers, but have broken off and are floating on a body of water.

Erosion is the result of processes that entrain and transport earth materials along coastlines, in streams, and on hillslopes. Wind and water are common agents Erosion results in the loss of valuable soil and its nutrients that are necessary for crops to grow. There are three primary kinds of erosion: wind, water, and tillage.
