Rock Cycle
| Term | Definition |
|---|---|
| Basalt | A dark, dense, igneous rock with a fine texture, found in oceanic crust. |
| Cementation | The process in which minerals precipitate into pore spaces between sediment grains and bind sediments together to form rock. |
| Compaction | The process by which sediments are pressed together under their own weight. |
| Deformation | When rocks change shape due to stress. |
| Deposition | Process by which sediment is laid down in new locations. |
| Erosion | Processes by which rock, sand, and soil are broken down and carried away (i.e. weathering, glaciation.) |
| Granite | A usually light colored igneous rock that is found in continental crust. |
| Igneous Rock | A type of rock that forms from the cooling of molten rock at or below the surface. |
| Limestone | A sedimentary rock consisting mainly of calcium that was deposited by the remains of marine animals. |
| Mantle | The layer of hot, solid material between Earth's crust and core. |
| Marble | Metamorphic rock that was once limestone. |
| Metamorphic Rock | Rock that has been changed by heat and pressure. |
| Metamorphism | The process by which rocks are changed in composition, texture, or structure by extreme heat and pressure. |
| Mineral | A naturally occurring solid that can form by inorganic processes and has a crystal structure and a definite chemical composition. |
| Quartzite | A metamorphic rock formed from sandstone. |
| Sandstone | A sedimentary rock made of sand held together by a natural cement. |
| Rock Cycle | A series of processes on the surface and inside Earth that slowly changes rocks from one kind to another. |
| Sediment | Small, solid pieces of material that come from rocks or living things. |
| Sedimentary Rock | A type of rock that forms when particles from other rocks or remains of plants and animals are pressed and cemented together. |
| Shale | A rock with a fine grain formed from clay, mud, or silt. |
| Slate | A type of metamorphic rock that was once shale rock formed by heat and pressure. |
| Weathering | The breaking down of rocks and other materials on Earth's surface. |
| Uplift | The rising of regions of the Earth's crust to higher elevations. |
| Sedimentation | The building up of layers of small particles like sand or mud. |
