Thus, soil erosion increases
rain.

Activity
Aim: To observe how loose soil gets carried away by wind.
Things needed: A pot with a plant growing in it, another pot with just dry sol
and a table fan
Method:
1. Take a potted plant and a pot with dry soil.
2. Place both in front of a table fan, such that the fan is blowing directly toward
3. Observe what the air does to the soil in both pots.
Observation: The pot without the plant loses a lot of its soil. Whereas the pot
growing in it does not lose much soil.
Conclusion: Plants prevent soil erosion.

Answer:
Soil erosion is the displacement of the upper layer of soil; it is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice (glaciers), snow, air (wind), plants, animals, and humans. In accordance with these agents, erosion is sometimes divided into water erosion, glacial erosion, snow erosion, wind (aeolean) erosion, zoogenic erosion and anthropogenic erosion such as tillage erosion.[1] Soil erosion may be a slow process that continues relatively unnoticed, or it may occur at an alarming rate causing a serious loss of topsoil. The loss of soil from farmland may be reflected in reduced crop production potential, lower surface water quality, and damaged drainage networks. Soil erosion could also cause sinkholes.
