What is soil erosion? How are human activities related to it?
Soil erosion is a naturally occurring process that affects all landforms; it’s like the disappearance or the wearing away of the topsoil layer. It’s a permanenet change of the main characteristics of soil.
Soil erosion’s supposed to happen naturally (eg. Harsh wind climate conditions, water erosions), but humans started to contribute to the cause.
Human activities such as overgrazing, overcropping and deforestation contributes to the effects of soil erosion.
