Correct Answer: Weathering

Solution : The correct option is weathering

Soil erosion is not caused by weathering. Weathering is the process of formation of soil by breaking down of rocks by the action of air,water and wind. Deforestation: When trees are cut down, the soil is exposed to wind and water. This can result in soil erosion. Overgrazing: When an area is grazed by too many animals, the plants that hold the soil in place are destroyed. This may also result in soil erosion. Poor agricultural practises: Ploughing following the contours of the ground, for example, can make it simpler for water to erode the soil.
