|---|---|
| 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 in which sediments are press together under their own weight |
| deformation | when rocks change shape due to stress |
| deposition | process in which sediment is laid down in new locations |
| erosion | process in 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 rock that forms at the cooling of molten rock at or below the surface |

| mantle | the layer of hot solid material between Earth's crust and core |
| marble | metaphoric rock that was once limestone |
| metamorphic rock | rock that has been changed by heat and pressure |
| metamorphism | the process in which rocks are changed in composition, texture, or structure by extreme heat and pressure |
| mineral | a naturally occurring solid that can form buy inorganic processes and has a crystal structure and a definite chemical composition |
| quartzite | a metamorphic rock formed from sandstone |
| sandstone | a sedimentary rock made out of sand held together by a natural cement |
| rock cycle | a series of processes on the surface 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 shale rock formed by heat and pressure |
