Geography

What is a constructive thrill? (1) These be long roves with short(p) energy, fracture at depositing material on the beach. Swash is greater than backwash. What is a destructive hustle? (1) Shorter drifts with lots of energy, drags sediment deal the beach. Stronger backwash than swash. Explain the formation of a tree stump (6) hydraulic action and abrasion erode the foreland creating an undercutting of drop pall base, which indeed forms a cockle cut notch. An overhang is created as the rove cut notch depends and the overhang cannot be back up so it collapses and the pass 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 arrive an arch. With continued erosion the arch widens and it cannot be supported the poll collapses forming a stack. More erosion undercuts the stack forming a stump as it collapses. Describ e the method of coastal comfortion shown (2) [picture of tilt armour] Large rocks placed at the bottom of the falloff to make whoopie 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 handsome rocks which are placed at the bottom of the cliff.

The rocks are every which way 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) T he wave cuts a wave cut notch in the headlan! d as it exploits a point of weakness. The force of gravity and dot of the rock causes it to collapse. Process starts again. After a series of cliff collapses a wave cut platform is left which is competent during low tide. Describe one method of a coastal protection (2) Sea Wall These are hard superlative walls which are built to reflect wave attack on the coast preventing erosion from the land behind often...If you want to embrace a full essay, order it on our website: OrderCustomPaper.com
