Earthquakes

media type="custom" key="10010151" width="144" height="144" align="left"﻿**//__Earthquakes__//** are sudden, violent shifting movements in the earth's crust that can release more energy than a nuclear bomb. During earthquakes, the land trembles and shakes, often violently enough to topple buildings and collapse bridges. Sometimes the land cracks open. ** Earthquakes are BOTH constructive and destructive **.

Earthquakes are caused when the **__//tectonic plates//__** that make up the earth's surface collide, separate, or scrape against each other. Because one plate can move faster or in a different diorection than another, the plates do not always slip smoothly past one another. When that happens, the earth's surface jerks and shifts along the plate boundries. These boundries are called //**__fault lines__**//. Not all fault lines are located on plate boundries.
