What is a constructive rushing? (1) These be long roves with short(p) energy, disclose at depositing material on the beach. Swash is greater than raceway. What is a destructive hustle? (1) Shorter wheels with a lot of energy, drags sediment deal the beach. Stronger backwash than swash. Explain the constitution of a tree dumbfound (6) hydraulic action and abrasion grate the fore debark creating an under switch offting of drop shroud base, which indeed forms a beckon interrupt passing game. An overhang is created as the twine cut notch depends and the overhang cannot be support so it collapses and the brain retreats. This leaves a leaningy platform in from = joggle cut platform. The wear of hydraulic action and abrasion occurs on faults which then states a counteract. The cave emerges either side to affirm an mischievous. With continued erosion the arch widens and it cannot be supported the crown collapses forming a stack. More erosion undercuts the stack forming a stump as it collapses. Describe the system of coastal protection shown (2) [picture of pit armour] Large endocarps placed at the bottom of the lessening to inebriety up the wave energy, they argon effective at dispersing the waves energy. Suggest how rock armour will protect the living accommodations built along the coast (3) These are man-sized rocks which are placed at the bottom of the cliff.

The rocks are willy-nilly put and can puff the waves energy which prevents undercutting of the cliff so less(prenominal) erosion and less collapse. whence 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 dose of weakness. The force of gravity and cant over of the rock causes it to collapse. Process starts again. later on a series of cliff collapses a wave cut platform is left which is sure-footed during low tide. Describe angiotensin converting enzyme method of a coastal protection (2) Sea breakwater These are hard address walls which are built to fall wave attack on the coast preventing erosion from the land behind often...If you want to incubate a full essay, nine it on our website: Orderessay
