What are the three horizon of a mature residual soil?

The three horizons of a mature residual soil are the A horizon (topsoil), B horizon (subsoil), and C horizon (weathered rock material). The A horizon contains organic matter and is the most fertile layer for plant growth. The B horizon is rich in minerals leached from the topsoil. The C horizon is the least weathered and consists of partially weathered bedrock.
