Erosion happens at the tops of mountains and under the soil. Water and chemicals get into the rocks and break them up through those mechanical and chemical forces. Erosion in one area can actually build up lower areas. Think about a mountain range and a river.

Where does erosion mostly occur?

Erosion occurs at the Earth's surface, and has no effect on the Earth's mantle and core. Most of the energy that makes erosion happen is provided by the Sun. The Sun's energy causes the movement of water and ice in the water cycle and the movement of air to create wind.

Can erosion happen anywhere?

Soil erosion is the natural process in which the top layer of soil is stripped away. While erosion can happen anywhere, it's especially a challenge on sloping land where water runoff is the most intense. Left unchecked, erosion can strip the topsoil from your property and compact the earth that remains.
