What are berms GCSE geography?
What is a recurved spit?
Hooked/Recurved spits. A spit whose end is curved landwards, into a bay or inlet. A hook or a recurve may form at the end of the spit. This is because wave refraction round the distal end transports and deposits sediment for a short distance in the landward direction.
What is the wave cut notch?
A wave-cut notch is formed by erosional processes such as abrasion and hydraulic action – this is a dent in the cliff usually at the level of high tide. As the notch increases in size, the cliff becomes unstable and collapses, leading to the retreat of the cliff face.
