Which description best matches a constructive wave?
Weak swash, strong backwash, about 13–15 waves a minute
Strong swash, weak backwash, about 13–15 waves a minute
Weak swash, strong backwash, about 6–8 waves a minute
Strong swash, weak backwash, about 6–8 waves a minute

In longshore drift, the swash moves up the beach at an angle. Why does the backwash move straight back down the beach?
The next wave pushes it back down
The prevailing wind pushes it back
The tide pulls it towards the sea
Gravity pulls it down the steepest slope
30s
Headlands and bays form most often on a coastline made of which arrangement of rock?
One band of hard rock running along the coast
Thick layers of a single type of rock
Alternating bands of hard and soft rock
Soft rock lying on top of hard rock
30s
Erosion on a headland eventually makes the roof of a sea arch collapse. What landform is left standing immediately afterwards?
A wave-cut notch
A stump
A stack
A cave
30s
A spit often has a curved (hooked) end. What usually causes this curve?
Destructive waves eroding its tip
The river current pushing it out to sea
A change in the wind and wave direction
Hydraulic action breaking the end off
30s
A spit grows right across a bay until it joins two headlands, forming a bar. What forms behind the bar?
A wave-cut platform
A sand dune ridge
A lagoon
A stack
30s
Groynes trap sand moving by longshore drift. What is a common negative effect of building them?
Waves become more constructive along the coast
Beaches behind the groynes become much narrower
Longshore drift changes to the opposite direction
Beaches further down the coast are starved of sand
