* Sedimentary Rock Formation: Sedimentary rocks are formed when loose sediments (like sand, clay, or shells) are transported, deposited, and then compacted and cemented together over time.
* Cementation: This process of "cementing" involves minerals dissolved in groundwater filling the spaces between the sediment particles. As these minerals crystallize, they act like glue, binding the sediments together to form solid rock.
Examples of sedimentary rocks formed by cementation:
* Sandstone: Formed from cemented sand grains.
* Conglomerate: Formed from cemented pebbles and larger rock fragments.
* Breccia: Similar to conglomerate, but the fragments are angular, indicating they haven't been transported far.
* Limestone: Often formed from cemented shells or marine skeletons.
* Shale: Formed from cemented clay particles.
