Slide 1 - Slide
What is the fetch?
A
when water flows back down the beach
B
when the swash is greater than the backwash
C
the distance of ocean over which the prevailing wind blows
D
destructive waves
Slide 2 - Quiz
What are the two types of waves?
A
swash and backwash
B
longshore and drift
C
abrasion and attrition
D
constructive and destructive
Slide 3 - Quiz
Which is true about longshore drift?
A
the swash occurs in the same direction as the prevailing wind direction
B
the swash moves at right angles
C
gravity determines the swash
D
the direction of longshore drift is the same direction as the backwash
Slide 4 - Quiz
the four types of coastal erosion are...
A
swash, backwash, constructive and destructive
B
hydraulic action, attrition, abrasion and solution
C
physical, chemical, biological, mechanical
D
cave, arch, stack, stump
Slide 5 - Quiz
What is the correct definition of hydraulic action?
A
pieces of rock nbash into each other becoming smaller, smoother and rounder
B
when pieces of rock and sand wear away the cliffs like sandpaper
C
when soluble particles are dissolved by water
D
when water forces air into the rock causing pieces to break away
Slide 6 - Quiz
Abrasion occurs when...
A
when water forces air into the rock causing pieces to break away
B
when soluble particles are dissolved by water
C
pieces of rock nbash into each other becoming smaller, smoother and rounder
D
when pieces of rock and sand wear away the cliffs like sandpaper
Slide 7 - Quiz
Bays and headlands form when...
A
there are different amounts of constructive and destructive waves
B
bands of harder and softer rock are present along a coastline
C
the cliffs are prone to different amounts of sliding and slumpin
D
different amounts of swash and backwash occur on a beach
Slide 8 - Quiz
What is the best description of a wave-cut platform?
A
A wide, gently sloping rock surface where cliff retreat has occurred
B
The distance of ocean over which the prevailing wind blows
C
A tall column of rock left when an arch collapses
D
A notch at the base of a cliff that has been eroded by the sea
Slide 9 - Quiz
What is the usual sequence of headland erosion?
A
Crack > Cave > Arch > Stump > Stack
B
Stack > Crack > Arch > Stump > Cave
C
Stump > Stack > Arch > Cave > Crack
D
Crack > Cave > Arch > Stack > Stump
Slide 10 - Quiz
Only one of these statements about headland erosion is true. Which is it?
A
When an arch collapses, it leaves a stack
B
Headlands are made from bands of soft rock
C
Caves erode further to become faults
D
When a stump collapses, it leaves a stack
