Soil Erosion➫ The removal of top layer of the soil by the action of wind & rainfall is called soil erosion.

♦ This is a naturally occurring process that affects all landforms.

❱ This natural process is caused by the dynamic activity of erosive agents like:-

♦ Water
♦ Ice
♦ Snow
♦ Air
♦ Plants
♦ Animals
♦ Humans

➧ Types of Erosion are:-
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=⤵

[1] Splash Erosion:-

❱ The first stage in the Erosion process.
Splash Erosion results from the bombardment of the soil surface by rain drops.

[2] Sheet Erosion:-

❱ The uniform removal of soil in thin layers by the forces of raindrops & overland flow.

[3] Rill Erosion:-

❱ The removal of soil by concentrated water running through little streamlet.

[4] Gully Erosion:-

❱ The removal of soil along drainage lines by surface water runoff.

➧ Causes 0f Soil Erosion are:-

❱ Water

❱ Winds

❱ Glacier

❱ 0ver Grazing

❱ Human Activities

➧ Factors that cause Soil Erosion are:-

❱ Rainfall

❱ Topography

❱ 0vergrazing

❱ Deforestation

❱ Human Activities

❱ Presence of 0rganic Materials in Soil

➧ Measures to Prevent Soil Erosion are:-

❱ Strip Farming

❱ Soil Rotation

❱ Soil Stabilisation

❱ Terrace Farming

❱ Vegetation Cover

❱ Controlled 0ver-Grazing

➧ Effects 0f Soil Erosion are:-

Answer 2

Answer:

India is home to two forms of erosion: sheet erosion and gully erosion.

Gullies cut the clayey soils into deep creeps, rendering the area unusable for farming and earning it the nickname "bad lands. Sheet erosion removes top soils across wide regions, which generally reduces production.

Explanation:

• Sheet erosion is the process of water flowing down a slope in a broad sheet. The top soil is lost to erosion.
• Sheet erosion is the term for this phenomenon. Deforestation and overgrazing, mining, building, etc. are three examples of human activities that cause soil erosion.

Soil erosion can be brought on by farming, grazing, mining, building, and leisure activities, among other things.
