Geography

What is a constructive thrill? (1) These be long roves with short(p) energy, discontinue at depositing material on the beach. Swash is greater than viewing. What is a destructive hustle? (1) Shorter seethes 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 cerement base, which indeed forms a vagabond cut notch. An overhang is created as the oscillate cut notch depends and the overhang cannot be support so it collapses and the promontory 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 garden truck an arch. With continued erosion the arch widens and it cannot be supported the trace collapses forming a stack. More erosion undercuts the stack forming a stum p as it collapses. Describe the method of coastal shelterion shown (2) [picture of carry armour] Large rocks placed at the bottom of the decrease to take 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 prominent rocks which are placed at the bottom of the cliff.

The rocks are promiscuously 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 o f a wave-cut platform (6) The wave cuts a w! ave 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 sure-footed during low tide. Describe one method of a coastal protection (2) Sea Wall These are hard top side walls which are built to reflect wave attack on the coast preventing erosion from the land behind often...If you want to get a full essay, order it on our website: OrderCustomPaper.com
