Pedosphere

The pedosphere ( to Greek pedon " soil ") is an earthly sphere and indicates the area occupied by soils of the Earth's surface in which the lithosphere, hydrosphere, atmosphere and biosphere overlap. One can also say that pedosphere includes the entirety of the soil of the planet Earth.

The overlap of litho -, hydro - atmosphere - biosphere and is reflected in the nature of the soils. The lithospheric intersection is formed from parent material of the soil: Is a rock exposed to atmospheric agents ( rain, weather or time of day induced temperature fluctuations, etc.) weathered it. The weathered rock mineral substance, mixed with aerobically decomposed organic matter, mainly supplied by plants is called the ground, the process of the formation of soils as soil formation.

Soils contained in the pore space of water and air, which represents the intersection of the lithosphere to the hydrosphere and atmosphere. Soil water and air interact with the mineral and organic matter, including in the form of solution or Ausfällungsvorgängen.

The Edaphon is the sum of living organisms in the soil and thus the biosphere intersection of pedosphere. It is indispensable for maintaining the organic matter cycles in the pedosphere and has also. Bioturbation by influence on the extent of interactions between the litho -, hydro-and atmospheric proportions of the soil

The depth ( thickness) of the pedosphere varies depending on climatic and morphological factors. In cold and / or dry climates and at high altitudes the pedosphere is rather low powerful, sometimes only a few centimeters, in a warm humid climate and in sinks more powerful, the range of several tens of centimeters. In particular, in the humid tropical soil can occur with widths of 50 meters and more.
