Soil is a layer of unconsolidated (i. e., loose) mineral and/or organic material. Soil is nearest to the Earth's surface in terrestrial areas (not covered by water). Soil makes up a very small percentage of the Earth's crust. It is a dynamic body, constantly undergoing change, made up of solid particles (e. g., mineral and organic), with voids in between that are filled with gases and water. Many definitions include a requirement that it must also support plant life in order to be called "soil." (8 pages)
