[1] [2] The sudden application of a torch to the surface of stone causes the surface layer to expand and flake off, exposing rough stone. Flaming works well on granite, because granite is made up of minerals with differing heat expansion rates.
Water is the principal agent behind both kinds, [1] though atmospheric oxygen and carbon dioxide and the activities of biological organisms are also important. [2] Biological chemical weathering is also called biological weathering. [3] The materials left after the rock breaks down combine with organic material to create soil.

Different specific granite types have differing propensities to weather, and so differing likelihoods of producing decomposed granite. The parent granite material is a common type of igneous rock that is granular, with its grains large enough to be distinguished with the unaided eye (i.e., it is phaneritic in texture); it is composed of ...
