Answer 1

There are multiple layers within soil. The topmost layer is the topsoil. Plants get minerals and organic matter, or humus, required for their growth from this layer.

Below this section is the subsoil, which is a mixture of sand, silt, and clay.

Third layer that has weathered rock material. Finally, the parent rock, which is also called the Bedrock, from which soil is formed is the bottom most layer.
