Landforms Of Coastal Deposition: Beaches Flashcards
What is a beach?
It’s a build-up or sand and shingle (small pebbles) that have been deposited by constructive waves between the high-water and low-water marks.
How can you find a beach on an OS map?

How are beaches formed?
When waves break, they lose energy and are unable to carry their load. The swash carries material up the shore and deposits it.
Why can’t the waves carry all the material back?
The backwash is weaker than the swash.
What material is dropped first?
The heaviest and then the finer material is carried closer to the coastline.
What happens during storms?
The waves get stronger and are able to carry heavy material such as boulders and rocks.
What is a storm beach?
The heavy material carried during storms are deposited above the high-water line.
