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. |
