What is Soil?
... Soil covers much of the land on Earth. All soils are made up of sand, silt, or clay. This describes the particle sizes, not the type of parent material it is composed of. Parent materials are the types of rocks and minerals it is derived from. Soils have other components: air, water and organic matt ...
