- Coastal Landforms caused by Deposition
- Beaches
- found on coasts between highest point on land the sea gets to, to the lowest point on land
- Formed by constructive waves depositing sand and shingle
- Sand beaches are flat and wide, back wash moves sand back down the beach creating a long and gentle slope
- Shingle Beaches are steep and narrow, backwash can't move shingle back down the beach creating a steep slope
- Spits and Bars
- Spits form at sharp bends in the coast line
- Longshore Drift transports material past the bend and deposits it in the sea
- Strong winds and waves can curve the end of the spit
- Lots of material is deposited behind the spit in the sheltered area - plants can grow and over time the area becomes a salt marsh or a mud flat
- Strong winds and waves can curve the end of the spit
- Longshore Drift transports material past the bend and deposits it in the sea
- Bars are formed when two headlands join together
- The bar cuts off the bay between the two headlands and forms a lagoon
- Spits form at sharp bends in the coast line
- Beaches
