Soil profile is the layers of soil. It has three layers — topsoil, subsoil and bedrock. Let's learn about them all.
1. Topsoil
2. Subsoil
3. Bedrock
Topsoil is the most fertile layer, as it contains humus. Strong winds and water, and human activity can carry topsoil to new places. This process of wearing off or carrying away of the topsoil by the action of wind or water is called soil erosion.
