Rock Cycle Vocab
Term | Definition |
---|---|
Basalt | A dark, dense, igneous rock with a fine texture, found in ocean 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 |
deposistion | process by which sediment is laid down in new locations |
erosion | processes by which rock, sand, and soil are broken down and carried away (ex: 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 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 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 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 |
