High and Low energy coastlines

Question 1

High

Answer 1

• Destructive waves
  
  • Exposed to strong winds and long fetches
  • Higher rates of erosion and deposition
  • Tend to be rocky coasts
  • Steep cliffs - marine cliff profile
  • Less steep cliffs - subaerial cliff profile
    Headlands, wave - cut platforms

Question 2

Low

Answer 2

• Constructive waves
  
  • Sheltered locations with short fetch
  • Higher rates of deposition than erosion
  • Sandy beaches, salt marshes, estuarine and tidal mud flats
  • Gentle relief
  • Sediment from land and sea
    Beaches, spits, coastal plains

Question 3

Coastal plains

Answer 3

They usually occur where the land gradually slopes down towards the sea, tend to be low relief

Coastal plains include both:
- Sandy coastlines
- Estuarine coastlines

Question 4

Primary coasts

Answer 4

dominated by land-based processes, such as deposition from rivers​

Question 5

Secondary coasts

Answer 5

dominated by marine erosion or deposition processes​
