Geology is the study of the Earth. Like so many scientific words, "geology" is constructed from root words dating back to ancient times: geo comes from the Creek word meaning "the Earth"; it is a prefix used in other related fields, too, such as geography, geodesy, and geophysics. The alogy suffix comes from the Creek logos, meaning "discussion," and is roughly translated as "the study of."

Bowen's reaction series is based on observations and experiments of natural rocks, the crystallization sequence of typical basaltic magma change as they cool. It is a sorting tool according to the temperature at which they crystallize common magmatic silicate minerals.

Fault is a fracture or crack where two rock blocks slide past one to another. If this movement may occur rapidly, it can be causes earthquike or slowly, in the form of creep.Types of faults include strike-slip faults, normal faults, reverse faults, thrust faults, and oblique-slip faults.
