| Term | Definition |
|---|---|
| Geology | The study of the origin history, structure and processes the shape earth |
| Inner core | A solid sphere in the middle of the fluid core such as the iron-nickle core of the earth |
| Outer core | Earths outer cored is a liquid layer about 2,266 km thick composed of iron and nickle that lies above Earths solid inner core and below its mantle |
| Mantle | Part of a terrestrial planet or other rocky body large enough to have differentiation by density |
| Plate Tectonics | Is a large scale motion of Earths lithosphere. It builds the concept of the continental |
| Pangaea | The hypothetical landmass that existed when all continents were joined, from about 300 to 200 million years ago |
| Continental Drift | The lateral movement of continents resulting from the motion of crustal |
| Divergent Boundaries | Place where plates move apart from each other |
| Convergent Bounderies | Place where plates collide |
| Transform Boundaries | Place where plates slide past each other |
| Wearthing | Break down lithosphere by wind. ice, plants, animals, and chemical change |
| Principle of Uniformity | Same process that happen in the past that are still happening today |
| Mechanical Wearthering | The process of breaking down rock into smaller pieces |
| Chemical Weathering | Process that alter mineral composition |
| Subsurface | The stratum or strata below the surface |
| Syncline | A downward fold rock structure |
| Anticline | An upward fold rock structure |
| Fault | Discontinuity is a volume of rock |
| Plateaus | An area of relatively level high ground |
| Epicenter | The point on the surface of the earths where an earthquake is first felt. Right above the focus |
| Focus | A crack in the Earths crust where earthquakes occur |
| Seismic Wave | Wave that travels out from an earthquakes |
| Primary Wave | Fastest wave in the subsurface that moves back and forth causes not a lot of damage |
| secondary wave | Slower wave in the subsurface that moves back and forth causes not a lot of damage |
| Surface Wave | Slowest wave on the surface that moves up, down and side to side causes high damage |
| Volcano | Areas of earths surface through which magma and volcano gases pass |
| Magma | Molten rock forced to earths surface |
| Lava | Magma flows into earths surface |
| Magma Chamber | Body of molten rock deep underground that feeds a volcano |
| Vents | Cracks in the earth crust to opening |
| Crater | A funnel shaped pit near the top of the central vent of a volcano |
| Caldera | A large semicircular depression that forms when magma chambers below a volcano partially erupts and causes the ground above to sink |
| Erosion | The process by which wind, water, ice, or gravity transports soil and sediment from one location to another. |
| Deposition | The process in which material is laid down. |
| Rock Cycle | The series of processes in which a rock forms, changes from one type to another, is destroyed, and forms again by geological processes. |
| Igneous rock | Rock's cooling by rock's and magma. |
| Sedimentary rock | Rock's formed throw depreciation and lairs . |
| Metamorphic rock | Rock that where once formed are now have change to anther by heat and presser. |
| texture | the quality of a rock this is based on the size shapes and position of the rock's grains |
| deposition | the prods in in which materiel is laid down |
| strate | layers of rock |
