Sand collects in shallow parts of the ocean like the place shown in (A). It is carried to the sea by rivers. The sand often forms ripples, like you can see in (A), and even underwater sand dunes and may eventually become layers of sedimentary rock called sandstone like that shown in (B).

How do people get to the shallow ocean? They scuba dive!
