What is Coastal Deposition and Landforms?
Within Geography, which covers maps, landforms, weather, climate, population and settlements: understand how our planet and people connect, this topic explains Coastal Deposition and Landforms. Geography explains how places, people and natural processes connect, so each topic here combines a clear definition with a visual model.
Check that you can explain Coastal Deposition and Landforms in your own words and give one example from everyday life. If you can do that, you have understood the core idea.
Understanding Coastal Deposition and Landforms helps you explain patterns on maps and in the news, and make reasoned decisions about places and environments.
Coastal Deposition and Landforms in detail
Constructive waves are low with a strong swash, so they deposit material, building up beaches of sand and shingle. Deposition occurs in sheltered areas such as bays where energy is low.
Longshore drift moves sediment along the coast in a zigzag, as waves approach at an angle but retreat at a right angle to the shore. Where the coast changes direction, it can build a spit, a long finger of sand, or a bar, which can close off a lagoon. Tombolos link islands to the mainland. These features change with storms and the supply of sediment.
