How is soil related to bedrock
WebBedrock lined with very deep decomposed volcanic soils form a barrier to water entry. Rain soaks into the upper layers of soil where it is held by humus and available to plants. In areas where badlands have formed, rainwater washes soil directly away, leaving dry bare rock that plants cannot hold onto (Scheman et al., 2002). Web3 jan. 2024 · The O horizon is the top layer at the earth's surface. It consists of surface litter, such as fallen leaves (duff), sticks and other plant material, animal waste and dead organisms. A distinct O horizon may not exist in all soil environments (e.g., desert soil). Below the O horizon is the A horizon, which is also known as topsoil.
