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 and grain and bind sediment to find rocks. |
| compaction | the process by which sediments are pressed together under there own weight. |
| deformation | when rocks change shape do to stress. |
| deposition | a process by which sediment is laid down in a new location. |
| erosion | processes by which rock, sand, and oil are broken down and taken away (I.e. weathering, glaciation. |
| granite | a usually light colored igneous rock is found in continental crust. |
| igneous rock | a type of rock that forms from 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 that was once limestone. |
| metamorphic rock | a rock that has Ben 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 metaphoric rock formed from sandstone. |
| sandstone | a sedimentary rock made from sand held together by natural cement. |
| rock cycle | a series of processes on the surface and inside the earth that slowly changes rocks from one kind from another. |
| sediment | small, solid pieces of material that comes from rocks or living things. |
| sedimentary rock | a type of rock that forms from other particles from 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 my 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. |
