UNDER A ROCK
Sedimentary is found below the ocean floor or area with water
An ocean stack is a piece of the mainland that extends out into the coast and is surrounded on 3 sides by water. It is pounded by the ocean waves which weather away the weaker pieces of sediment and rock forming it into a jagged piece of rock that juts up from the ocean. Eventually the ocean currents will cause the remaining rock and sediment away.
Salt in the ocean comes together and makes a rock.
