TBSHS GCSE Geography: Coasts Quiz 5

Which government department is responsible for the protection of the coastline from flooding and erosion in England and Wales?

• Department for Education

• Department for Transport

• Department for Environment, Food and Rural Affairs

• Department for Business, Energy and Industrial Strategy

The Environment Agency and local governments work together to manage sections of coastline.

There are currently 4 policy options:

• No intervention

• Toe the line

• Hold the line

• Managed realignment

• Advance the line

Soft engineering:

• Involves building artificial defences to interrupt natural processes.

• Examples include beach nourishment and sand dune regeneration.

• Allowing coastal processes to work and the land to change in a more environmentally sustainable way.

• Examples include groynes and rip rap.

Hard engineering:

• Involves building artificial defences to interrupt natural processes.

• Examples include beach nourishment and sand dune regeneration.

• Allowing coastal processes to work and the land to change in a more environmentally sustainable way.

• Examples include groynes and rip rap.

Coastal management techniques - sea wall.

Choose the correct statement(s)

• They are effective at stopping the sea from eroding cliffs.

• They are a cheap way to protect the coast.

• They often have a promenade which people can use to exercise.

• They work with natural processes.

Coastal management techniques - groynes.

Choose the correct statement(s)

• Interrupting the movement of sediment has an impact further along the coast.

• They are a cheaper than a sea wall.

• They trap sediment and widen the beach.

• They are an example of soft engineering.

Coastal management techniques - rock armour (rip rap).

Choose the correct statement(s)

• The rocks force waves to break, absorbing wave energy.

• They can impede access to the beach.

• A bigger beach can attract more tourists.

• Boulders are usually from outside the local area, so transport costs can be high.

Coastal management techniques - sand dune regeneration.

Choose the correct statement(s)

• Areas of the beach have to be fenced off, prohibiting access.

• Relatively cheap.

• It maintains a natural coastal environment.

• All of the statements are correct.

Which of the following distinctive landforms are formed primarily due to the process of deposition?

• Headlands

• Beaches

• Spits

• Bars

Longshore drift

Choose the statements which apply most appropriately to this process.

• This is the process of erosion which moves sand and pebbles along the coast.

• Material is moved along the coast in a zigzag way.

• The backwash moves sediment straight back down the beach due to gravity.

• Prevailing winds bring waves in at an angle to the coast.
