Geography

What is a constructive thrill? (1) These be long roves with short(p) energy, mitigate at depositing material on the beach. Swash is greater than washout. What is a destructive hustle? (1) Shorter wavings with lots of energy, drags sediment deal the beach. Stronger backwash than swash. Explain the formation of a tree dumbfound (6) hydraulic action and abrasion erode the foreland creating an undercutting of drop mantle base, which indeed forms a boom cut notch. An overhang is created as the turn over cut notch depends and the overhang cannot be support so it collapses and the brain 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 upraise an arch. With continued erosion the arch widens and it cannot be supported the diadem 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 controversy armour] Large rocks placed at the bottom of the decrease to throw 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 tumid rocks which are placed at the bottom of the cliff.

The rocks are arbitrarily 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 platfo rm (6) The wave cuts a wave cut notch in th! e headland as it exploits a point of weakness. The force of gravity and pourboire of the rock causes it to collapse. Process starts again. After a series of cliff collapses a wave cut platform is left which is overt during low tide. Describe one method of a coastal protection (2) Sea Wall These are hard covert walls which are built to reflect wave attack on the coast preventing erosion from the land behind often...If you want to cocker a full essay, order it on our website: OrderCustomPaper.com
