Rock Cycle
| Question | Answer |
|---|---|
| Rock Cycle | processes undergone by rocks in the earth's crust, involving igneous intrusion, uplift, erosion, transportation, deposition as sedimentary rock, metamorphism, remelting, and further igneous intrusion. TERM |
| weathering | The chemical and physical processes that break down rock at Earth's surface. |
| erosion | - the process of carrying away material that has been broken down by wind, water, ice, and gravity |
| deposition | Process in which sediment is laid down or dropped off in new locations. |
| sedimentary rock | forms when particles from other rocks or the remains of plants and animals are compacted/ pressed and cemented together |
| igneous rock | forms when magma/lava cools, crystallizes and solidifies |
| metamorphic rock | forms from an existing rock that is changed by heat, pressure, or chemical reactions. |
| uplift | The process that moves large bodies of Earth materials to higher elevations |
| subsidence | the sinking of regions of the Earth's crust to lower elevations |
| rift zone | an area of deep cracks that forms between two tectonic plates that are pulling away from each other |
| magma | molten rock below the Earth's surface |
| lava | molten rock/magma above surface |
| intrusive igneous | formed from the cooling and solidification of magma beneath Earth's surface |
| extrusive igneous | forms from the cooling and solidification of lava at Earth's surface |
