| 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 stress |
| 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 ( i.e. weathering, glaciation) |

| marble | metamorphic rock that was once limestone |
| metamorphic rock | rock that has been changed by the heat and pressure |
| metamorphism | the process by which rocks are changed in composition, texture, or structure by extreme heat and pressure |
