Longshore Drift:
Longshore Drift is the transportation of sand and pebbles along the coast.
The direction the wind usually flows from, also known as the prevailing wind, causes ways to approach the cost at an angle. The sand and pebbles are then carried by swash at the same angle, (usually 45 angle). swash is the white foamy water that rushes up the coast, because of the pull of gravity and friction, the water flows back towards the sea. On the other hand, the backwash carries the materials back down the beach at a 90 degree angle, The reason being, this is the steepest gradient. Imagine if a pebble was placed in the water, it would then be carried along the coastline in a zigzag motion, this will cause it to eventually be deposited when there
