Ask.com Answer for: what causes a earthquake
Earthquakes are caused by an abrupt shift of rock along a fracture in the Earth.
Most earthquakes are caused by slow movements inside the Earth that push against the Earth's brittle, relatively thin outer layer, causing the rocks to break suddenly.
The movement of two of the Earth's plates, or layers, is what causes an earthquake. The two plates move and either run into each other or slide past each other. You can find more information here: http://earthquake.usgs.gov/learn/kids/eqscience.php
