Here's a breakdown:
* Sedimentary rocks are formed from the accumulation and cementation of sediments.
* Sediments are fragments of pre-existing rocks, minerals, or organic matter.
* Cementation is the process where dissolved minerals in groundwater precipitate out and bind sediment particles together, forming a solid rock.
There are many types of sedimentary rocks, depending on the type of sediment and the cementing minerals involved. Some common examples include sandstone (cemented sand grains), limestone (cemented calcium carbonate), and shale (cemented clay particles).
