The set of all chemical reactions that can act on rock exposed to water and the atmosphere and so dissolve the minerals or change them to more stable forms.
The breaking down of surface rock material by solution or chemical alteration. Common alteration processes are oxidation and hydrolysis.
Chemical reactions that act on rocks exposed to water and the atmosphere so as to change their unstable mineral components to more stable forms. Oxidation, hydrolysis, carbonation, and direct solution are the most common reactions.
the process of weathering by which chemical reactions transform rocks and minerals into new chemical combinations (compounds). One example is the chemical weathering of feldspars into clays (muds).
Erosion as a result of a liquid ( usually rain water) flowing over a rock causing a chemical reaction that dissolves the rock's minerals and washes them away. For example, acid rain dissolves calcium carbonate out of the limestone. The resultant water is calcium carbonate rich and can be deposited as calcite elsewhere e.g. as a stalactite in a cave.
The process by which chemical reactions alter the chemical composition of rocks and minerals that are unstable at the Earth's surface and convert them into more stable substances; weathering that changes the chemical makeup of a rock or mineral. See also mechanical weathering.
The process that changes the chemical makeup of a rock or mineral at or near the Earth's surface. Chemical weathering alters the internal structure of minerals by the removing and/or adding elements. Compare with mechanical weathering. more details...
The use of chemicals to crack and split rocks into smaller pieces.
The breakdown of rocks and minerals due to the presence of water and other components in the soil solution or changes in redox potential.
the process that changes the composition of rock, forming new minerals that have properties different from those of the original rock
The breakdown of rock material brought about by the action of chemicals, usually in aqueous solution.
Breakdown of rock and minerals into small sized particles through chemical decomposition.
