Sedimentary Rocks
Term | Definition |
---|---|
Sedimentary | a rock that has formed from sediment deposited by water or air |
Compaction | Particles are smashed together with such great force that they stick together |
Cementation | Water moving between particles carries dissolved minerals that can act as cement, when minerals slowly precipitate out of water and fill the spaces between the particles |
Clastic | rocks that are composed of other older broken rocks |
Chemical/ Crystalline | rocks formed by precipitation of minerals from water |
Bioclastic Sedimentary | Sedimentary rocks that contain the remains of organisms ex: Limestone, Coal |
Grain Size | the size of the sediment particles |
Precipitate | rocks that are formed when water has more dissolved minerals than it can hold, minerals then settle out of the water |
Evaporates | rocks that form due to water evaporating and leaving minerals behind |
Environment of Formation | the area, temperature and other factors that were present when a rock was created |
