GEOLOGY

Detailed explanation-1: -Detailed Solution. The correct answer is Afforestation. Afforestation is not a cause of soil erosion.

Detailed explanation-2: -Soil is the material which is formed as the result of wethering hence it is not the agent of wethering and this is the right answer.

Detailed explanation-3: -Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. Water, acids, salt, plants, animals, and changes in temperature are all agents of weathering and erosion.

Detailed explanation-4: -Weathering can be caused by wind, water, ice, plants, gravity, and changes in temperature.

Detailed explanation-5: -Erosion occurs because of factors like wind, water, ice, human activities like deforestation etc. Weathering, on the other hand is caused by contact with the earth’s atmosphere. These atmospheric conditions may be heat, pressure etc.
