2B.3B- Dunclue case study

Question 1

Describe the tectonics (dip) at Dunclue Castle

Answer 1

Near horizontal/slightly dipping landward strata (-17o)

Question 2

Describe the geology of dunclue castle

Answer 2

100% Basalt (agglomerate) near cliff
25% Chalk near sea

Question 3

Describe the wave energy at dunclue castle

Answer 3

High tide
Constructive waves (0.7

Question 4

Describe sub-aerial/marine processes at dunclue castle

Answer 4

Variable sub-aerial weathering (higher degradation in bay)

Question 5

What is marine erosion

Answer 5

Often at headland sites
Wave cut notch and platform formation
Rate of erosion/debris varies over time

Question 6

What is sub-aerial weathering

Answer 6

Often at the backshore of bays
Refraction means lower marine energy
Cliff degradation increases from above

Answer 8

tectonics and geology

Question 9

What is a variable factor affectign morphology

Answer 9

wave energy and sea level rise (climate change)
