Soil has 3 major layers or horizons. The top layer is known as topsoil or the surface horizon. The second layer is subsoil. The third layer is called the substratum, but some might also call it bedrock. You can find more information here: http://soils.usda.gov/education/resources/K_12/lessons/profile/
