Coastal Environments

 

Which of the following descriptions correctly describe low energy waves?

• High wave height and frequency

• Generated far offshore by prevailing winds

• Powerful swash helps to build beaches

• Spilling breakers due to gently shelving sea floor

Which process involves wave fronts bending around and focusing wave energy on headlands, whilst dissipating it in bays?

• Wave backwash

• Wave translation

• Wave refraction

• Wave breaking

Which type of coastal erosion involves pebbles and shingle being thrown against a cliff?

• Hydraulic Action

• Abrasion

• Attrition

• Solution

Which of the following processes are sub-aerial?

• Mass movement

• Cavitation

• Chemical weathering

• Biological weathering

 

Which of the following factors result in increased erosion of the coast?

• Steep destructive waves breaking at the cliff face

• Strong tides and longshore drift that moves material quickly

• Well jointed and faulted rocks dipping towards the shore

• Offshore bars causing waves to break before reaching the shore

If the cliffs in this coastal zone were protected with a seawall, how would it affect the sediment cell?

• The offshore bars and banks would increase in size

• Inputs of material would decrease overall, causing erosion

• Longshore drift would transport more material across the estuary, creating a bar

• The sand dunes would decrease in size

Which of these descriptions correctly describes feature A in this photograph?

• A wave-cut platform created by the retreat of a headland

• Found in the inter-tidal zone

• Will rise over time due to deposition

• Found on low energy coastlines

Which of the following descriptions correctly describes the coastal zone shown in the photograph?
