Coastal Erosion, Transportation & Deposition Flashcards

All 6 cards in this deck

What is hydraulic power (hydraulic action) at the coast?: The power of waves smashing onto a cliff; trapped air is forced into holes and cracks, eventually breaking the rock apart.
What is abrasion (corrasion) at the coast?: Fragments of rock are picked up and hurled by the sea at a cliff, wearing it away.
What is attrition?: Rock fragments carried by the sea knock against each other, becoming smaller, smoother and rounder.
What is longshore drift?: The zigzag movement of sediment along a coast: swash carries material up the beach at an oblique angle, backwash returns it at right angles.
Give two reasons why sediment is deposited in coastal areas.: The flow of water slows down (e.g. in sheltered bays or where the coast changes direction), or friction with a gently sloping seabed reduces wave energy.
True or false? The direction of longshore drift is determined by the direction of the prevailing wind.: True. Waves follow the prevailing wind and hit the coast at an oblique angle, moving material in that direction.
