Here's why:
* Deposition: This is the process where sediments, like sand, silt, clay, or even the remains of organisms, are dropped or settled in a new location.
* Cementation: This happens after deposition. Minerals dissolved in groundwater precipitate between the sediment particles, acting like glue to bind them together and solidify the sediment into a solid rock.
Some common examples of sedimentary rocks include:
* Sandstone: Formed from cemented sand grains.
* Limestone: Formed from cemented shells and other marine organisms.
* Shale: Formed from cemented clay particles.
