| Term | Definition |
|---|---|
| Basalt | A dark, dense , igneous rock with a fine texture, found in oceanic crust. |
| Cementation | The process by 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 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 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 crystal structure and a definite chemical composition. |
| Quartzite | A metamorphic formed by 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 form other rocks or the 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 buj heat and pressure. |
| Weathering | The breaking down of rocks and other materials on the 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. |
