Document Summary

Chemical weathering: causes the decomposition, decay or rotting of minerals, chemical changes occur, caused by internal disruptive forces (e. g. reaction of mineral to water, energy and water drive these processes, hydrolysis - occur when minerals are moistened. Causes chemical alteration, but expansion as well, which contributes to breakdown of rocks. E. g. feldspar hydrolysis yields clay minerals and (bi)carbonates: oxidation - occurs when minerals in rocks react with oxygen. Opposite reaction is "reduction" (removal of oxygen). E. g. when carbonic acid comes in contact with carbonate rocks such as limestone it reacts to produce calcium bicarbonate, which is water soluble and is removed in solution. E. g. acid precipitation forms nox and sox gases dissolve in rainwater. Precipitation in the atmosphere is naturally acidic (ph of around. Physical weathering: also known as mechanical weathering, causes disintegration of rocks without chemical change to minerals, caused by external disruptive forces (e. g. growth of ice in rock cracks)
