Geography

What is a constructive thrill? (1) These be long roves with short(p) energy, reveal at depositing material on the beach. Swash is greater than wash. What is a destructive hustle? (1) Shorter reels with lots of energy, drags sediment deal the beach. Stronger backwash than swash. Explain the formation of a tree vex (6) hydraulic action and abrasion erode the foreland creating an undercutting of drop winding-clothes base, which indeed forms a totter cut notch. An overhang is created as the boom cut notch depends and the overhang cannot be support so it collapses and the point retreats. This leaves a leaningy platform in from = wave cut platform. The erosion of hydraulic action and abrasion occurs on faults which then states a cave. The cave emerges either side to realise an arch. With continued erosion the arch widens and it cannot be supported the peak collapses forming a stack. More erosion undercuts the stack forming a stump as it collapses. Descr ibe the method of coastal entertainion shown (2) [picture of wave armour] Large rocks placed at the bottom of the slack to befuddle 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 king-sized 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 platform (6) The wave cuts a wave cut notch in the headland ! as it exploits a point of weakness. The force of gravity and topple of the rock causes it to collapse. Process starts again. After a series of cliff collapses a wave cut platform is left which is open(a) during low tide. Describe one method of a coastal protection (2) Sea Wall These are hard inter walls which are built to reflect wave attack on the coast preventing erosion from the land behind often...If you want to beat a full essay, order it on our website: OrderCustomPaper.com
