Why do beaches have rocks instead of sand?
When erosion happens on ocean cliffs, it is because there are strong waves crashing into the cliffside, causing the breaking down of the cliff. As a result, the pieces of rock or pebbles from these cliffs are carried to shorelines, creating rock beaches rather than sand.
