6&7. Coastal Landscape Development

Question 1

What are the key factors and processes that impact coastal landscape development?

Answer 1

Geology
Climate
Nature of tides and waves
High/low energy input
Human activity

Question 2

How does geology impact the coastal landscape development?

Answer 2

Coastal configuration- headlands attract wave energy due to wave refraction
Rock characteristics- resistant rocks like chalk erode more slowly than weak rocks like clay
Structure- cracks and fissures can be exploited
Concordant/discordant coastlines

Question 3

How does climate impact coastal landscape development?

Answer 3

Temperature ranges lead to more freeze-thaw weathering

Wet climates lead to slope failure

Question 4

How does the nature of waves and tides impact coastal landscape development?

Answer 4

Steeper waves are higher energy
Long fetch produces more powerful waves
Sea depth- steep shelving will create higher and steeper waves

Question 5

What are the three ways of classifying coasts?

Answer 5

Concordant and discordant
Cliffed, flat or graded shoreline
Emergent and submergent

Question 6

What is a concordant coastline?

Answer 6

One with rocks running parallel to it

Question 7

What is a discordant coastline?

Answer 7

One with rocks running at right angles to it
Creates headlands and bays
