Quiz Answer Key and Fun Facts
1. What compass direction are the waves coming from that affect the south coast of Britain?

Answer: South Westerly

On Britain's southern coast, waves come in at a 45 degree angle from a south westerly direction. It changes when it is the northern coastline.
2. At what angle do swash waves come in on the British coastline?

Answer: 45 degrees

On any coastline of Britain the swash will come in at 45 degrees.
The swash wave is the incoming wave which when at its peak can erode most substances.
3. If the incoming wave is called a swash wave, what is the outgoing wave called?

Answer: Backwash

This catches high school students and adults alike, there is no 's', backwash, quite confusing!
4. At what angle does an outgoing wave enter the sea?

Answer: 90 degrees

The backwash re-enters the sea at 90 degrees, usually taking material such as sand with it.
5. Sea defences are used to stop longshore drift, ruining beaches across the British coast. Which of these sea defences, built perpendicular to the shore, is often made of wood?

Answer: Groynes

Groynes are usually wooden fences situated about 15m apart from each other along a beach.
6. What landform is caused at a deposition point?

Answer: Spit

A spit is formed when water loses its energy and deposits material at a deposition point. Spits constantly change in shape. Spurnhead spit near Hull and Grimsby is a prime example!
7. Which of these is a form of erosion?

Answer: Corrasion

It is described as being an erosional form, when rocks are thrown onto the coastal areas in storms.
8. What is the name of the type of erosion that is distinguished by water entering a crack or crevice of a rock and eventually weakening it and cracking it further?

Answer: Hydraulic action

Hydraulic action usually causes undercutting of a cliff and eventually a landslide.
9. When does the pattern of longshore drift stop?

Answer: When the land changes shape dramatically

Landforms such as headlands and peninsulas change the pattern of longshore drift.
10. Is the city of Plymouth, Devon affected by longshore drift?

Answer: Yes, all of coastal Britain is

I hope you enjoyed and learned a thing or two about Britain's coastline and the theory of longshore drift.
