Changing landscapes

Part 1: Erosion and deposition

We think of a mountain as something that never changes. And yet it is constantly changing. The wind, the cold and water are cutting and shaping it every day. All around us the land is slowly changing. Erosion is cutting away the land in one place but deposition is building new land in a different place.

The process of marine erosion and deposition happens because of the action of the sea on rocks. Destructive waves are strong waves that attack the coast. They cause erosion and they transport material. The waves throw sand and pebbles at the cliffs. This breaks up the land into more rocks, pebbles and sand. Then the sea carries this material away. Constructive waves are weaker and can't carry the material far. They deposit the material in a different place. In this way bars and beaches are formed.

Part 2: Headlands and bays

Bands of soft rock erode more quickly than bands of hard rock. This leaves sections of land going out into the sea. When there are bands of hard rock and soft rock, we often find headlands and bays.
