Hazards

Question 1

what affects how you perceive a hazard?

Answer 1

• wealth
• experience
• education
• religion and beliefs
• mobility

Question 2

what is fatalism?

Answer 2

view that hazards are uncontrollable natural events so losses should be accepted as nothing can be done

Question 3

5 active responses to hazards

Answer 3

prediction - scientific research and past events so warnings can be delivered
adaption - alternating lifestyle choices to live with hazards
mitigation - strategies carried out to lessen severity of a hazard
management - coordinated strategies, includes predication, adaption and mitigation
risk sharing - community preparedness, where community shares risk posed by a natural event and invests collectively to mitigate impacts e.g. new Zealand has insurance investment

Question 4

what are the three types of hazards

Answer 4

• geophysical = caused by land processes
• atmospheric = caused by atmospheric processes
• hydrological = caused by water bodies and movement

Question 5

what hazards are harder to predict

Answer 5

low incidence hazards are harder to predict and less management strategies are put in place so they can be catastrophic when they occur

Question 6

what is the park model

Answer 6

a model showing the 3 stages of human response to hazards carried out in the recovery of a place
curve steepness shows how quickly a place deteriorates and recovers
depth of curve shows the scale of the disaster

Question 7

structure of Earth’s inner core

Answer 7

solid ball of iron/nickel
hot (pressure and radioactive decay)
heat responsible for Earth’s internal energy

Question 8

structure of Earth’s outer core

Answer 8

semi molten
iron/nickel

Question 9

structure of the mantle

Answer 9

solid rock + high in silicon
very top is semi molten magma (asthenosphere)
lithosphere rests on top

Question 10

structure of the lithosphere

Answer 10

broken into plates majority within mantle
top is the crust

Question 11

structure of the crust

Answer 11

thin top of lithosphere
oceanic crust = dense and destroyed by plate movement
continental crust = less dense and not destroyed
