Beaches and Sand | manoa.hawaii.edu/ExploringOurFluidEarth
Factors other than wave energy also determine sand grain size at a beach. The size of sand grains is related to the slope of the beach. For example, the steeper the beach, the larger the sand grain size tends to be. This is because larger particles can be cast higher up the beach by the waves on steep beaches. On flatter beaches, however, sand ...
