| sedimentary rock | type of rock forms when particles from other rocks or the remains of plants and animals are pressed and cemented together |
| metamorphic rock | a type of rock that forms from an existing rock that is changed by heat, pressure, or chemical reactions |
| texture | the look and feel of a rocks surface determined by the size and shape and pattern of a rocks grains |
| grains | a particle of mineral or other rock that gives a rock its texture |
| sediment | small, solid pieces of material that comes from rocks or organisms |
| erosion | the destructive process in witch water of wind lossen and carry away fragments of rock |
| deposition | the process by which sediment settles out of the water or wind that it's carrying |
| compaction | the process by which sediments are pressed together under their own weight |
| cementation | the process by which dissolved minerals crystallize and glue particles of sediment together in one mass |
| organic rock | sedimentary rock that forms where remains of organisms are deposited in thick layers |
| clastic rock | sedimentary rock that forms when rock fragments are squeezed together under high pressure |
| chemical rock | sedimentary rock that forms when minerals crystallize from a solution |
| rock cycle | a series of processes on the surface and inside Earth that slowly change rocks from one kind to another |
