| outer core | Fourteen to eighteen hundred miles from earths center |
| mantle | Semi solid rock |
| Crust | A large block of tabular section of the lithosphere |

| Convergent | Place where plates collide |
| Transform | Place where plates slide past each other |
| Weathering | The breaking down of earths lithosphere by of wind ice plants and chemical changes |
| Principle of uniformity | The process that changed the world and still changing |
| Chemical weathering | Process that affects mineral composition |
| Mechanical weathering | The break down of rock into smaller pieces |
| Subsurface | Below the surface |
| Anticline | The upward fold in rocks |
| Syncline | The downward fold in rocks |
| Fault | Split of crust |
| Plateau | Flat area of land |
| Epicenter | The point on the surface where the earthquake is first felt |
| Focus | The point where an earthquake starts |
| Seismic wave | Waves that travels out from an earthquake |
| Primary waves | The first and fastest seismic wave |
| Surface wave | The slowest wave on surface also |
| Secondary wave | The Escondido fastest seismic wave |
| Volcano | Are the area on earths surface through which magma and volcanic gasses pass |
| Magma | Molten material beneath the earths crust |
| Magma chamber | A body rock deep underground that feeds a volcano |
| Lava | The molten fluid rock issues volcano or volcanic vent |
| Vents | A opening at the surface of one earth could volcanic material passes |
| Pyroclastic flow | Are produced when enormous amounts of ash dust and gases are ejected from a volcano |
| Viscosity viscous | The state or quality of being viscous |
| Rock Cycle | Is a group of changes between rocks. |
| Erosion | the process which wind water ice or gravity transports soil and sediment form one location to another. |
| Deposition | the process in which material is laid down. |
| Met-amorphous rock | Rock that was once one formed and now have changed to another by heat and pressure. |
| Igneous Rock | rocks formed by cooling of lava and magma. |
| Sedimentary rocks | Rocks formed through deposition and sediments in layers. |
| Extrusive igneous rocks | Rocks that form as a result of volcanic activity at or near the earths surface. |
| Intrusive igneous rocks | rock formed from the cooling and solidification of magma beneath the earths surface |
| strata | layers |
| Index Minerals | Used to estimate the temperature and depth and the which a rock goes under metamorphism\ |
| foliated | The texture of metamorphism rock in which the mineral grains are arranged in planes or bands |
| nonfoliated | The texture of metamorphic rock in which the mineral grains are not arranged in planes or bands |
