The lithosphere is divided into a dozen major and several minor plates. The movement of the plates over Earth’s surface is called plate tectonics. These plates can be composed in a combination of oceanic lithosphere or continental lithosphere. An earthquakes epicenter is the point on Earth’s surface directly above the place where the earthquake occurs. Earthquake epicenters outline the plates because earthquakes occur everywhere plates come into contact with each other.
Mantle convection drives plate movement
Plate Boundaries are the areas where two plates meet. The type of plate boundary and the type of crust found on the boundary determines what kinds of geologic activity are present.
