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."

An unconformity is contact between two rock units.Unconformities are typically buried erosional surfaces that can represent a break in the geologic record of hundreds of millions of years or more. It it called an unconformity because the ages of the layers of rock that are abutting each other are discontinuous at the unconformity. An expected age of layer or layers of rock is/are missing due to the erosion; and, some period in geologic time is not represented.

Plate tectonics is a scientific theory that explains the movements and behaviors of the Earth's lithosphere, which is composed of the crust and uppermost...
