Soil is the mixture of minerals , organic matter , gases, liquids, and the countless organisms that together support life on Earth. Soil is a natural body known as the pedosphere and which performs four important functions: it is a medium for plant growth; it is a means of water storage , supply and purification; it is a modifier of Earth's atmosphere ; it is a habitat for organisms; all of which, in turn, modify the soil.
Soil is considered to be the "skin of the Earth" and interfaces with its lithosphere , hydrosphere , atmosphere, and biosphere . Soil consists of a solid phase (minerals and organic matter) as well as a porous phase that holds gases and water. Accordingly, soils are often treated as a three- state system of solids, liquids, and gases.
Soil is the end product of the influence of the climate , relief (elevation, orientation, and slope of terrain), organisms, and its parent materials (original minerals) interacting over time. Soil continually undergoes development by way of numerous physical, chemical and biological processes, which include weathering with associated erosion .
