What are coasts?
Coasts are when the land meets the sea. The coastlines of the UK is made up from cliffs, beaches and bays.
How are beaches formed?
Beaches are formed when the cliffs erodes (broken down by the sea). The large rocks fall of the land and get tossed around in the sea. The rocks are eroded and get smaller and smaller until the rocks become tiny particles, called sand. Some beaches have pebbles and not sand. This is because the sea hasn’t broken down the rocks quite so much.

What causes tides?
Tides happen daily. Have you ever been to a beach when the tide comes in? The water seems to creep up the beach making the beach smaller. The tides are caused by the gravitational pull between the sun and the moon.
