CAUSES OF EARTHQUAKE - DEFINITION
Earthquakes happen deep underground along tectonic plate boundaries. Tectonic plates are what make up the earth's crust, its outermost layer. They are always moving because the part of the earth underneath them is like a fluid. However, each plate is lined up pretty well with the other plates around it. So as they move, they create tension and pressure as they slide past and bump into each other. These forces are felt on the surface of the earth as an earthquake.
