The size of particles that make up a beach are often a reflection of the energy of the waves that hit the shore. Sandy beaches are usually found in bays where the water is shallow and the waves have less energy. Pebble beaches often form where cliffs are being eroded and where there are higher-energy waves.

Why does England have rocky beaches?

The famous pebble beaches along the south coast of England are often composed of flint derived from the chalk cliffs that are found locally. The chalk is dissolved in the sea water leaving the flint behind and this combined with the steeply sloping shoreline gives us the pebbly beaches.

Where is the Supralittoral zone?

The supralittoral is above the high-tide mark and is usually not under water. The intertidal or littoral zone ranges from the high-tide mark (the maximum elevation of the tide) to the shallow offshore waters.

Why do periwinkles stick to rocks?

Periwinkles cling tightly to rocks during low tide. Periwinkles use their operculum to seal up the opening to their shell not only to avoid desiccation but also to avoid predators. When the water returns periwinkles use their muscular foot to hold securely onto the substrate when waves crash over the rocks.
