One part of science that is looked at in middle school is the coasts. Children will already understand that coasts are where the land and the sea meet, and now they will be taught about some of the geographic features that are found there, such as beaches, cliffs and bays.

Coasts are the edges of the land. The coast is the place where land and sea meet. There are special environmental features on the coast. Coasts are also places people meet for their holidays, where they can sunbathe on the beach, paddle in the sea and explore rockpools and caves.

See how much you know about coastal environments and the features that can be found there by playing this quiz.

When a cave erodes further and forms a tunnel through the cliff
When a rock is pushed by waves and becomes rounded
Arches are caves that have worn all the way through a cliff. They look almost man made
4.
