Explanation:

The human activities that lead to soil erosion are deforestation and agriculture.

Explanation:

Soil erosion (the wearing away and displacement of the topsoil) may be caused by natural factors such as strong winds, water, ice and animals, or by human activities that make the soil weak.

Deforestation is the logging or burning of trees for the purpose of construction or the usage of wood for several activities (heating or paper-making). When they remove the vegetation, they leave the upper layer of soil (topsoil) unprotected against winds and water.

Agriculture is the activity of growing crops for the production of food. When farmers plant their vegetation, they remove the topsoil and this is mostly carried away by winds into water streams (they become sediments).
