Rock Cycle
Term | Definition |
---|---|
Basalt | a dark dense, igneous rock with 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 by which sediments are together under their own weight. |
Deformation | when rocks change shape due to stress. |
Deposition | process by which sediments 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 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 a shale rock formed by 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. |
