Earthquakes and Volcanoes occur when tectonic plates are moving. Tectonic plates are pieces of the earths crust and upper mantle. Earthquakes are cause when the rock underneath us suddenly breaks along a fault. The release of energy and the vibration causes the ground to shake. Small earthquakes occur everyday but it is not noticeable to the average person. When one plate goes under the other one and magma from the mantle works its way to the surface. When pressure builds
