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!
