• errode beaches and coastal habitates
• damage coastal defences
• contaminate farmland and fresh water areas (lakes)

Question 4

Coastal flooding

Answer 4

The combination of intense rainfall and storm surges = areas at sever risk of flooding. Affects farming and tourism industries
- environmental impact-effect farming and tourism industries

Question 5

Landslides

Answer 5

high levels of rainfall can saturate the soil very quickly. This makes the soil very heavy and in some ares, can slide down a slope.

• cause massive devastation to settlement at the base of the slope
• cause river flooding if the landslide blocks the river
