These be long roves with short(p) energy, better at depositing material on the beach. Swash is greater than backwash.
What is a destructive hustle? (1)
Shorter waves with lots of energy, drags sediment deal the beach. Stronger backwash than swash.
Explain the formation of a tree stump (6)
hydraulic action and abrasion erode the foreland creating an undercutting of drop curtain base, which indeed forms a wave cut notch. An overhang is created as the wave cut notch depends and the overhang cannot be supported so it collapses and the headland retreats. This leaves a leaningy platform in from = wave cut platform. The erosion of hydraulic action and abrasion occurs along faults which then states a cave. The cave emerges either side to produce an arch. With continued erosion the arch widens and it cannot be supported the jacket collapses forming a stack. More erosion undercuts the stack forming a stump as it collapses.
Describe the method of coastal protection shown (2) [picture of rock armour]
Large rocks placed at the bottom of the cliff to drink up the wave energy, they are effective at dispersing the waves energy.
Suggest how rock armour will protect the living accommodations built along the coast (3)
These are large rocks which are placed at the bottom of the cliff.
The rocks are randomly put and can absorb the waves energy which prevents undercutting of the cliff so less(prenominal) erosion and less collapse. Therefore the cliff wont retreat back.
Explain the formation of a wave-cut platform (6)
The wave cuts a wave cut notch in the headland as it exploits a point of weakness. The force of gravity and tip of the rock causes it to collapse. Process starts again. After a series of cliff collapses a wave cut platform is left which is capable during low tide.
Describe one method of a coastal protection (2)
Sea Wall These are hard cover walls which are built to reflect wave attack on the coast preventing erosion from the land behind often...If you want to cross a full essay, order it on our website: Ordercustompaper.com
