| sediment | pieces of solid rock that has been deposited on Earth's surface |
| clastic | type of sedimentary rock that consists of broken pieces of other rocks cemented together |
| deposition | the process of laying down sediment of Earth's surface |
| lithification | the process of making more of earth's crust |
| cementation | the process of gluing mineral grains together to form sedimentary rock |
| porosity | the amount of open spaces in a material |
| regional metamorphism | heat and/or pressure that affects large areas of Earth's crust turning igneous or sedimentary rock into metamorphic rock |
| contact metamorphism | occurs when magma comes in contact with rock and changes its composition to form a metamorphic rock |
| hydrothermal metamorphism | occurs as water, heated from Earth's mantle comes in contact with rock and changes its chemical composition, making it a metamorphic rock |
| rock cycle | the process of rocks turning into other types of rock |
