Q.1
Constructive waves are most likely to occur on which sort of beach?
  • A flat or shallow beach
  • A steep beach
  • A beach with sheer cliffs and a strong wave action
  • A beach that is heavily used for tourism
Q.2
Depostion occurs when waves lose energy and deposit their load. Which of the following is another reason that deposition is likely to occur?
  • Waves enter an area of shallow water
  • There is little or no wind
  • Waves enter a large open area, such as moving from a bay to the open sea
  • There is a large amount of material to be deposited
Q.3
Which of the following is a method of coastal transportation?
  • Erosion
  • Solution
  • Suspension
  • Traction
Q.4
What sort of shape should a constructive wave have?
  • A steep crest with a short wavelength
  • A high wave in proportion to its length with a tall breaker
  • A low wave height and a long wavelength
  • A long wavelength and a steep breaker
Q.5
Backwash is when a wave washes back down the beach. What do we call the opposite, when the wave washes up the beach?
  • Longshore drift
  • Swash
  • Deposition
  • Constructive
Q.6
What is a tombolo?
  • A spit connecting an island to the mainland
  • A beach with a lake behind it
  • A type of lagoon
  • A type of headland that terminates at a different type of rock
Q.7
What is longshore drift?
  • The process where a reef is eroded on the upstream side and deposited on the downstream side, gradually moving it along the coast
  • The process that forms a high-tide line on a beach of flotsam and jetsam, as material is deposited by the movement of waves in and out
  • The transportation of sediments (clay, silt, sand and shingle) along a coast at an angle to the shoreline, in a zig-zag pattern
  • When a boat or other object comes to rest on a sandy shore material builds up downstream of the hull, and is eroded from upstream
Q.8
In terms of backwash and swash, when is deposition most likely to occur?
  • When backwash is equal to swash deposition is more likely to occur
  • When backwash is stronger than swash deposition is more likely to occur
  • Deposition occurs in neither swash nor backwash
  • When swash is stronger than backwash deposition is more likely to occur
Q.9
Some beaches are protected by an offshore landform known as a reef. Which of the following is a way reefs may form?
  • Sand banks build up as material is deposited away from the beach
  • Cliffs erode unevenly and leave behind land after arches collapse
  • Coral based creatures grow at the point of optimal light growth
  • Beach protection measures are artifically constructed to protect the land or provide leisure opportunities
Q.10
Spurn Head is a famous coastal spit across the mouth of the River Humber. The material that has built up the spit is the result of longshore drift. Why has this spit formed at this location?
  • The change in currents as the river enters the sea causes more energy to enter the system
  • The pollution coming down the river is deposited at this point. This allows the material moving down the coast to build up here
  • There is a natural reef at this point that material builds up on, aided by longshore drift
  • The energy in the waves and the river is reduced at this location causing the material to be deposited
