2.10 - Human/Physical Factors and Recession (Guinea)

Question 1

State physical factors which affect Guinea’s recession

Answer 1

SLR due to climate change

Swell waves

Question 2

State three human factors which affect Guinea’s recession

Answer 2

Diamond mining
Sand extraction
Coastal management/dredging

Question 3

How do SLR affect Guinea?

Answer 3

Risen 10cm since 1950 leading to more destructive waves, erosional processes and so erosion also stronger backwash

Question 4

Why are mangrove forests being cut down?

Answer 4

Used as fuel for household needs

Question 5

Effect of diamond mining?

Answer 5

Gravel is extracted from rivers but it isn’t returned

Means that there’s less sediment transported to the coastline and less to absorb wave energy

Question 6

Why is mangrove deforestation bad?

Answer 6

Height/energy of waves can’t be reduced and soil is washed away as there are no root systems to bind soil

Question 7

How do swell waves affect Guinea?

Answer 7

Swell waves reach 3m during monsoon (Aug to Oct) leading to $3.8m damage and unemployment (farmland)

Question 8

How do strong waves have an effect?

Answer 8

Break on soft cliff material so more is eroded as less resistant rock
