Here are some examples:
* Sedimentary rocks: Rocks formed from the accumulation and cementation of sediment.
* Sedimentary environment: A place where sediment is deposited, such as a river bed or a lake.
* Sedimentary processes: The processes that lead to the formation of sedimentary rocks.
While "sedimentary" can sometimes be used as a noun, it's less common and usually refers to a specific type of rock.
For example, you might say: "The geologist studied the sedimentaries of the Grand Canyon."
However, it's more common to use the phrase "sedimentary rocks" instead.
