GENERAL GEOLOGY

Detailed explanation-1: -There are three major subdivisions of geology, physical geology, historical geology, and environmental geology.

Detailed explanation-2: -The realm of geochemistry extends beyond the Earth, encompassing the entire Solar System, and has made important contributions to the understanding of a number of processes including mantle convection, the formation of planets and the origins of granite and basalt. It is an integrated field of chemistry and geology.

Detailed explanation-3: -Some major fields closely allied to geology are geodesy, geophysics, and geochemistry.

Detailed explanation-4: -Geochemistry is the branch of Earth Science that applies chemical principles to deepen an understanding of the Earth system and systems of other planets. Geochemists consider Earth composed of discrete spheres-rocks, fluids, gases and biology-that exchange matter and energy over a range of time scales.
