Transportation & Deposition Landforms

Question 1

The most common depositional landform is a beach

how do beaches form

Answer 1

Beaches build up due to constructive waves

They form in sheltered areas such as bays

Beach formation is more common in summer when there are fewer destructive waves

Question 2

Depositional landforms occur at

Answer 2

low energy coastlines when the waves do not have enough energy to carry a large sediment load

Question 3

Drift-aligned beaches form

Answer 3

where longshore drift moves the sediment along the beach as waves approach at an oblique angle

This will often culminate in a spit where the coastline changes direction

Question 4

Swash-aligned beaches form where the

Answer 4

energy is low

The waves are more parallel to the shore in swash aligned environments so there is little horizontal or lateral movement of sediment

Question 5

Salt marshes and san dunes are also
