Dynamics of the Earth

Insolation, the effects of water, groundwater, springs

Geological factors external dynamics of the Earth:
-Radiation from the Sun-insolation,
-Water,
-Snow and ice,
-Effects of organisms

Insolation-illumination

Insolation to heat the rocks in the lithosphere and leads to expansion of certain mineral constituents.Stretching is not uniform because of various physical and chemical properties of minerals that build a rock, and is not uniform in depth of rock (on the surface is more intense).At night when there is no sunshine ,rocks cools and tightens.

Multiple repetition of heating and cooling of the cohesion forces between mineral-poor, resulting microcracks and cracks that are increasingly wider and deeper, until it finally came to the disintegration of rock.
Resistance of rocks to the impact of insulation depends on the mineral composition, structure and texture of rocks, vegetation, thickness of cover, relief and climate characteristics.
Effect of insolation is more pronounced in areas with large temperature differences between day and night in Coarse heterogeneous composition of the rocks.

WATER-atmospheric, surface and groundwater

Water participates in the destruction (physical and chemical)of rocks, transportation and accumulation of fragments and particles, thus affecting the characteristics of relief:
-in a humid area of its physical and chemical attack is most prominent,
- in the glacial area, works mostly mechanical (glaciers, rock disintegration by freezing water in cracks),
-in the arid area mechanically destroying the mechanism fragments and particles at small distances, and participates in the chemical dissolution of rock.
