Often at the edge of the sea there are cliffs high mountains, which give a great view over the sea. But they can also be dangerous, especially if they are eroded, when rocks and earth fall away into the sea. Most people prefer sandy beaches rather than pebble beaches beaches with small stones. Sometimes, behind sandy beaches you can see sand dunes - areas of sand that the wind blows into small hills. Often, different types of grasses grow in the sand dunes.
