| Tsuamis | Earthquakes that occur on the ocean floor are tsunamis. |
| Earth Quakes | An earth quake is the shaking and trembling that results from the sudden movement of part of the Earth's crust. |
| Focus | The focus is the underground point of origin of an earthquake. |
| epicenter | Directly above the focus, on the earth's surface, is the epicenter. |
| Seismic Waves | There are three types of Seismic waves.Each type wave has a characteristic speed and manner of travel. |
| Primary Waves | Seismic waves that travel the fastest are called primary waves |
| Seismic waves | Earthquake waves are known as seismic waves. |
| Secondary Waves | Seismic waves that do not travel through the Earth as fast as P waves do are called secondary waves. |
| Surface Moves | The slowest moving seismic waves are called surface waves. |
| Siesmograph | A seimograph is an instrument that detects and measures seismic waves . |
| Seismologists | Scientist who study earthwquakes |
| Seimogram | The seismographs record of waves is called a seismograph. |
| Richter Scale | THe height of the tallest wavy lines on a seismogram is used to calculate the strength of an earthquake on the Richter scale |
| Magma | Deep within the Earth ,under tremendous pressure and at extreme temperatures, rock exists as a hot liquid called magma. |
| Lava | molten rock outside of the earth |
| Volcano | The place in the Earth's surface through which magma and other materials each the surface and the magma becomes lava is called a volcano. |
| Volcanic ash | Rock particles more than 0.25 millimeter but less than 5 millimeters in diameter are called volcanic ash. |
| Volcanic Bombs | Larger rock particles are called volcanic bombs. |
| Cinders | Small volcanic bombs about the size of a golf balls are called cinders. |
| Cinder Cones | Volcanoes made mostly of cinders and other rock particles that have been blown into the air are called cinder cones. |
| Shield Volcanoes | Volcanoes composed of quit lava flows are called shield volcanoes. |
| Composite Volcanoes | Volcanoes built up of alternative layers of rock particles and lava are called composite volcanoes. |
| Crater | There is often a funnel-shaped pit or depression at the top of a volcanic cone.This pit is called a crater. |
| Caldera | If a crater becomes very large as a result of the collapse of its walls, it is called a caldera. |
| Ring of fire | The sans andreas fault is part of this zone.This zone that circles the Pacific Ocean is called the Ring of Fire. |
