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 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 sress |
deposition | process by which sediment is laid down in new locations |
erosion | processes by which rock sand and soil are broken down and carried away |
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 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 hear and pressure |
mineral | a naturally occurring solid that can form by in organic 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 the earth that slowly changes rocks from one 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 |
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 the building up of layers of small particles like sand or mud |
