Year 11 coasts revision

What is the fetch?

1. when water flows back down the beach
2. when the swash is greater than the backwash
3. the distance of ocean over which the prevailing wind blows
4. destructive waves

What are the two types of waves?

1. swash and backwash
2. longshore and drift
3. abrasion and attrition
4. constructive and destructive

Which is true about longshore drift?

1. the swash occurs in the same direction as the prevailing wind direction
2. the swash moves at right angles
3. gravity determines the swash
4. the direction of longshore drift is the same direction as the backwash

the four types of coastal erosion are...

1. swash, backwash, constructive and destructive
2. hydraulic action, attrition, abrasion and solution
3. physical, chemical, biological, mechanical
4. cave, arch, stack, stump

What is the correct definition of hydraulic action?

1. pieces of rock nbash into each other becoming smaller, smoother and rounder
2. when pieces of rock and sand wear away the cliffs like sandpaper
3. when soluble particles are dissolved by water
4. when water forces air into the rock causing pieces to break away

Abrasion occurs when...

1. when water forces air into the rock causing pieces to break away
2. when soluble particles are dissolved by water
3. pieces of rock nbash into each other becoming smaller, smoother and rounder
4. when pieces of rock and sand wear away the cliffs like sandpaper

Bays and headlands form when...

1. there are different amounts of constructive and destructive waves
2. bands of harder and softer rock are present along a coastline
3. the cliffs are prone to different amounts of sliding and slumpin
4. different amounts of swash and backwash occur on a beach

What is the best description of a wave-cut platform?

1. A wide, gently sloping rock surface where cliff retreat has occurred
2. The distance of ocean over which the prevailing wind blows
3. A tall column of rock left when an arch collapses
4. A notch at the base of a cliff that has been eroded by the sea

What is the usual sequence of headland erosion?

1. Crack > Cave > Arch > Stump > Stack
2. Stack > Crack > Arch > Stump > Cave
3. Stump > Stack > Arch > Cave > Crack
4. Crack > Cave > Arch > Stack > Stump

Only one of these statements about headland erosion is true. Which is it?

1. When an arch collapses, it leaves a stack
2. Headlands are made from bands of soft rock
3. Caves erode further to become faults
4. When a stump collapses, it leaves a stack
