The type of rock that forms from sediment like sand, dirt, mud, clay, gravel, and stone is called sedimentary rock.

Here's a breakdown:

* Sedimentary rocks are formed by the accumulation and cementation of sediments. These sediments can be:

* Clastic: Made up of fragments of other rocks (like sand, gravel, pebbles, etc.)

* Chemical: Formed from the precipitation of minerals from water solutions (like limestone, rock salt)

* Organic: Formed from the remains of organisms (like coal, some types of limestone)

So, whether it's a sandy beach, a muddy riverbed, or a layer of gravel, over time and under pressure, these sediments can solidify into sedimentary rock!
