An area of land that smells different to other places.
d)
An area that has a lot of wind.

5.
What is the first stage of a stack forming from a head land?
a)
Cracks erode to form a cave.
b)
Hydraulic action creates small cracks in the headland/cliff face.
c)
The cave becomes wider and deeper.
d)
The waves cut through the cave and form an arch.
6.
What is the most advanced stage of erosion of a headland?
a)
Cracks erode further to create a cave.
b)
The roof of an arch becomes too heavy and collapses.
c)
The cave becomes wider and deeper.

Abrasion.
c)
Attrition.
d)
Solution.
8.
What is swash?
a)
Water that runs back into the ocean.
b)
Water that falls forward and moves up the shore.
c)
Tug of war between the drag of the wind and pull of gravity.
d)
Swirling of water in an area.
9.
What is backwash?
a)
Water that runs back into the ocean.
b)

10.
What are destructive waves?
a)
Waves that are tall and frequent, crashing into shoreline, digging out chunks.
b)
Long and low waves, beginning far out in the sea, with a smooth gentle landing.
c)
The circular movement caused by wind and gravity fighting.
d)
When people wave their hand to aggresively destroy things.
11.
What are constructive waves?
a)
Waves that are tall and frequent, crashing into shoreline, digging out chunks.
b)
Long and low waves, beginning far out in the sea, with a smooth gentle landing.
c)
The circular movement caused by wind and gravity fighting.

12.
Waves are created by wind
a)
True
b)
False
13.
The "fetch" is the strength of the wind
a)
true
b)
false
14.
If a wave is constructive then the backwash is stronger than the swash
a)
true
b)
false
15.
Hydraulic action is when air becomes trapped in joints and cracks on a cliff face and then a wave breaks, the trapped air is compressed which weakens the cliff and causes erosion.
a)
true
b)
false
16.
Continual swash and backwash transports material sideways along the coast. This movement of material is called longshore drift and occurs in a zigzag.
a)
true
b)
false
17.
