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 sediments are pressed together under their own weight |
deformation | when rocks change shape die to stress |
deposition | process by which sediments its 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 bot solid material between earths 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 define chemical composition |
Quartzite | a metamorphic rock formed from sandstone |
sandstone | a sedimentary rock made of sand held together by natural cement |
rock cycle | a series of processes in 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 forms when particles \from other rocks or remains of plants and animals are pressed and cemented together |
shale | a rock with fine grain formed from clay mud or slit |
weathering | the breaking down of rocks and other materials on earths surface |
uplift | the rising of the earths crust to higher elevations |
sedimentation | the building up of layers of small particles like sand or mud |
