The pedosphere is the outermost layer of the Earth that is composed of soil and subject to soil formation processes. It exists at the interface of the lithosphere, atmosphere, hydrosphere and biosphere. Earth (often referred to as the Earth, Terra or Planet Earth) is the third planet in the solar system in terms of distance from the Sun, and the fifth largest. ...

Life is found pervasively on the pedosphere (soil) surface, the land surface of the lithosphere, in the hydrosphere (oceans, lakes and rivers), extending down to various depths into the pedosphere and lithosphere, and up into the lower atmosphere.
The pedosphere is comprised of relatively thin soil layers found on top of much of Earth's land surface.
A number of processes operating on a variety of time scales occur in the pedosphere: heat, water, gas, and energy transfers, biological activities, weathering and erosion, compaction, salinization, biogeochemical cycling, organic matter decomposition and humus formation, and soil genesis.
