A shingle beach (or pebble beach) is a beach made of pebbles, not sand. The stones may be from 2 to 200 millimetres (0.1 to 7.9 in) diameter. These beaches strongly resist erosion by waves.
This beach landform is quite common in Western Europe, because the pebbles come from the lines of flint in the chalk. Chesil Bank is an example. When the chalk erodes, the tough flint stays as pebbles.
