Soil is a mixture of tiny pieces of rock, minerals, water, air, and organic matter that supports plant growth. It is made up of layers including topsoil with humus and organisms, subsoil with some humus and rock pieces, and underlying bedrock. Soil types are classified by the size of particles as sand, silt, or clay which determine properties like texture, drainage, and ability to retain water and air.
