The Big Geography Quiz of the Year

COASTS Round 6

Question 1 Name 1 form of erosion

Question 2 When a wave has a strong swash it is called a: Constructive wave Destructive wave

Question 3 Name 3 types of hard engineering that help to protect coasts from erosion.

Question 4 Explain what longshore drift does to sediment on a beach

5. Question 5 This is Reynisfjara in Iceland. What sort of coastal erosion landform is this?

Question 6 Name 1 type of soft engineering that is used to reduce the impact of coastal erosion and/or flooding.

7. B A C Question 7 This is Capelinhos in the Azores. Name the coastal features at point A, B, C?

Question 8 How does hydraulic action work? A) When waves pick up beach material (e.g. pebbles) and hurl them at the base of a cliff. It is commonly known as the sand paper effect. B) When waves cause rocks and pebbles to bump into each other and break up into smaller, more rounded pieces. C) When waves hit the base of a cliff air is trapped in the cracks. This compresses air until the rocks crack and break away under pressure. D) When certain types of cliff erode as a result of weak acids in the sea.

Question 9 Name a landform created by coastal deposition.

Question 10 The distance that the wind blows a wave across the sea is called the: Prevailing wind Fetch Gale

Answers: Coasts Round 6 Hydraulic action, attrition, abrasion, corrosion Constructive wave Sea wall, groynes, rip rap, gabions, offshore reefs, revetment Longshore drift transports/moves sediment along the beach due to prevailing winds Sea stacks Beach replenishment, cliff plantation/stabilisation, dune shaping/regeneration, creating marshland, managed retreat/coastal realignment A= bay/beach, B = headland, C = stump C Spit, bar, tombolo, beach B - Fetch
