What is a constructive thrill? (1) These be long roves with short(p) energy, let on at depositing material on the beach. Swash is greater than wake. What is a destructive hustle? (1) Shorter sways with lots of energy, drags sediment deal the beach. Stronger backwash than swash. Explain the formation of a tree tree stump (6) hydraulic action and abrasion erode the foreland creating an undercutting of drop mantel base, which indeed forms a curl up cut notch. An overhang is created as the wave cut notch depends and the overhang cannot be support so it collapses and the principal 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 call down an arch. With continued erosion the arch widens and it cannot be supported the beg collapses forming a stack. More erosion undercuts the stack forming a stump as it collapses. Describe the method of coastal encourageion shown (2) [picture of leaning armour] Large rocks placed at the bottom of the falloff to drink in 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 gargantuan rocks which are placed at the bottom of the cliff.

The rocks are indiscriminately 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 sufficient during low tide. Describe one method of a coastal protection (2) Sea Wall These are hard wield walls which are built to reflect wave attack on the coast preventing erosion from the land behind often...If you want to stick a full essay, order it on our website: OrderEssay.net
