Weathering of Rocks: Physical and Chemical Geology

2021-7-4  Chemical weathering is a process in which rocks are broken down changing their chemical compositions. Most of the rocks are formed in an environment very much different from the environment prevailing at the surface of the earth. Many of the substances present in the atmosphere are not present in the environment where the rocks are formed.

Lithograph. Lithography is a planographic printmaking process in which a design is drawn onto a flat stone (or prepared metal plate, usually zinc or aluminum) and affixed by means of a chemical reaction. First, the design for the lithograph is drawn directly onto a polished slab of limestone using an oil-based lithographic crayon or ink.
