Term | Definition |
---|---|
Geology | The study of earth and its origin history |
Inner Core | earth's inner core earth's innermost part and is a primary solid ball |
outer core | Fourteen to eighteen hundred miles from earths center |
mantle | Semi solid rock |
Crust | A large block of tabular section of the lithosphere |
Tectonic Plates | like jigsaw puzzle pieces |
Continental drift | The gradual movement of earths continents toward or away from each other |
Pangaea | Supercontinent |
Divergent | Place where plates move apart |
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 |
