Explanations: answer key for all 10 questions

Q1: What is the main cause of coastal erosion?
Answer: Waves
Storms make waves more powerful.
Q2: What is the usual order of coastal landforms as a headland erodes?
Answer: Cave, arch, stack, stump
Waves widen weak spots over time.
Q3: What are the Twelve Apostles in Australia?
Answer: Sea stacks
Several have collapsed.
Q4: What is longshore drift?
Answer: Sand moving along the coast
Waves hit at an angle.
Q5: What landform does longshore drift build?
Answer: A spit
Spurn Head in England is one.
Q6: What is a groyne?
Answer: A barrier that traps sand on a beach
It slows longshore drift.
Q7: What is a downside of sea walls?
Answer: They can increase erosion nearby
Wave energy is pushed elsewhere.
Q8: What is managed retreat?
Answer: Letting the coast move inland on purpose
It can restore marshes.
Q9: Which English coast is one of Europe's fastest eroding?
Answer: Holderness
It loses about 2 meters a year.
Q10: How does sea level rise affect erosion?
Answer: It lets waves reach farther inland
Stronger storms add to it.

Coastal Erosion Trivia Quiz – Shrinking Shores

Coastal erosion is the wearing away of land by waves, currents and storms. Waves pound cliffs, hurl sand and stones and force air into cracks, slowly breaking rock apart.

On rocky headlands, erosion carves caves that become arches, then stacks and stumps, such as Australia's Twelve Apostles. Waves also move sand along beaches by longshore drift, building spits and bars elsewhere.

People defend coasts with sea walls, groynes and rock armor, or use softer methods like beach nourishment and managed retreat. Rising sea levels and stronger storms are speeding erosion, putting homes and roads at risk worldwide.
