A ravine is a deep narrow valley on earth’s surface formed by running water, e.g. Chambal ravine in Madhya Pradesh.
Due to the formation of gullies, the land becomes unfit for cultivation and is known as bad land.
The running water cuts through clayey soils and makes deep channels, called gullies.
The natural forces which lead to soil erosion are wind, glacier and water.
Foundation of Kankar layers restricts water infiltration into the arid soils.
Arid Soil develops due to high temperature and evaporation.
