Coastal processes & landforms

Answers and reasoning. Review before teaching.

1. What is the zigzag movement of sand and shingle along a coastline caused by waves approaching the beach at an oblique angle: longshore drift or continental drift?
Longshore drift
Swash moves sediment up the beach at an angle and backwash pulls it straight down, transporting material along the shore.
2. Why do headlands and bays form along a discordant coastline: alternating bands of hard rock (which erodes slowly into headlands) and soft rock (which erodes rapidly into bays) meet the coast, or all rocks have identical hardness?
Alternating bands of hard rock (which erodes slowly into headlands) and soft rock (which erodes rapidly into bays) meet the coast
Differential erosion leaves resistant rock jutting out as headlands while softer clay or sand is hollowed into sheltered bays.
3. What is the forward rush of foaming water up a beach after a wave breaks: swash or backwash?
Swash
Swash carries sand and shingle up the beach slope in the direction of the breaking wave.
4. What curved concrete wall is built along the back of a shoreline to reflect wave energy and protect coastal roads and buildings from flooding: a sea wall or a groyne?
Sea wall
Curved sea walls deflect breaking waves back toward the sea.
5. Which type of low-frequency, gentle wave has a strong swash and a weak backwash, building up sandy beaches: a constructive wave or a destructive wave?
Constructive wave
Constructive waves deposit more sediment up the beach than they remove.
6. What is the return flow of water draining back down the beach toward the sea under gravity: backwash or swash?
Backwash
Backwash flows straight down the beach slope at right angles to the shoreline.
7. When a sand spit grows all the way across a bay to connect two headlands, trapping a shallow freshwater or brackish lake behind it, what is the ridge called: a bar (bay bar) or a cave?
Bar (bay bar)
A bar seals off the entrance to a bay, enclosing a coastal lagoon behind it.
8. Which coastal erosion process occurs when waves hurl pebbles and sand against a cliff base like sandpaper: abrasion (corrasion) or attrition?
Abrasion (corrasion)
Rock fragments carried by waves grind and scrape away the cliff rock.
9. As a cliff retreats inland through repeated undercutting and collapse, what gently sloping rocky ledge is left behind at low tide: a wave-cut platform or a lagoon?
Wave-cut platform
A wave-cut platform is the broad rock bench exposed at the base of a retreating cliff.
10. What is the correct sequence of landforms created as waves erode a weakness in a rocky headland: Crack → Cave → Arch → Stack → Stump, or Stack → Arch → Cave → Crack?
Crack → Cave → Arch → Stack → Stump
Waves widen a crack into a sea cave, cut through the headland to form an arch, collapse the arch roof to leave a stack, and erode the stack into a stump.
11. Which coastal erosion process occurs when breaking waves trap and compress air inside cracks in a cliff face, shattering the rock: hydraulic action or solution?
Hydraulic action
The sudden compression and explosive release of air in rock joints wedges fragments loose.
12. In tropical oceans, what ring-shaped coral reef encloses a central lagoon after the central volcanic island has gradually subsided beneath the sea: an atoll or a fjord?
Atoll
As a volcanic island slowly sinks, upward-growing fringing coral reefs evolve into a barrier reef and finally a ring-shaped atoll.
