Weathering of Rocks: Types, Factors and Products Geology
WitrynaTemperature variations and organic activity are two important factors that bring about this change under specific conditions. Temperature variations are held responsible for extensive mechanical weathering of rocks exposed on the surface. This manifest in three different ways: (a) Frost action in cold humid regions, WitrynaMechanical Weathering How do organisms contribute to mechanical and chemical weathering? Any organic activity such as tree roots growing in cracks contributes to mechanical weathering Organic acids and the tendrils of mosses and lichens aid in the chemical alteration of parent material.
