Sedimentary rocks are one of the three different rock types. They are created at or around the surface of the earth. Sedimentary rock is made of sediments which are particles that can be carried through liquid flows. They are the most common rock on land. Around 70-80% of rocks on land are sedimentary. Common types are Limestone, Shale, and Conglomerate. Sedimentary rocks are made from sediments that compact and turn into rock during lithifiction caused by overburden pressure.
