Coastal Landscapes Quiz

What is the backshore in a coastal zone?

• Area submerged at high tide

• Zone of wave breaking

• Nearshore sediment zone

• Area only affected by waves during storms

The nearshore zone is best defined as:

• Dry sand dunes behind the beach

• Offshore zone beyond wave action

• Area above the high tide line

• Area where waves break and sediment is moved

What characterises the offshore zone?

• Where longshore drift occurs

• Between high and low tide

• Where swash dominates

• Beyond the influence of breaking waves

Why is the coastal zone considered dynamic?

• It is protected from erosion

• It changes only every 100 years

• It is controlled by fixed tectonic processes

• It is influenced by marine, atmospheric and human factors

Which of the following is a short-term change?

• Sea level rise from climate change

• Isostatic rebound

• Coastal uplift from tectonic activity

• Storm surge flooding

A Dalmatian coast is an example of:

• Raised beach system

• Emergent landform

• Barrier island coastline

• Submerged parallel ridges and valleys

A Haff coast forms through:

• Coral reef growth

• Erosion of parallel headlands

• Flooding of glacial troughs

• Deposition of bars creating lagoons

Headlands and bays form due to:

• Sea level change

• Sand dune formation

• Wave refraction patterns

• Differential erosion of rock types

Constructive waves are associated with:

• Steep, narrow beaches

• High backwash energy

• Cliff collapse

• Deposition and wide beach profiles

Destructive waves tend to:

• Build berms

• Be low energy

• Occur in sheltered bays

• Have strong backwash and erode beaches
