chance of someone being affected by a natural hazard
2 of 21
name 3 factors increasing the risk of natural hazards
urbanisation, climate change, poverty, farming
3 of 21
how does urbanisation increase the risk of natural hazards?
more people live in highly populated areas, so more people will be affected by natural hazards
4 of 21
explain how poverty increases the risk of natural hazards
their poverty may force them to live in areas at risk, they can't get the help they need when they are affected
5 of 21
how does climate change increase the risk of natural hazards?
wetter parts of the world will cause more flooding
warmer parts of the world will cause more droughts

describe what happens at a constructive plate margin
plates move apart, new crust is formed as magma rises to the surface
7 of 21
describe what happens at a destructive plate margin
plates move towards each other. oceanic plate may sink beneath a less dense continental plate.

give 4 reasons why people choose to live in hazardous areas
rich minerals can be obtained, people living in poverty can't live in wealthier areas, unaware of the risks of plate margins, favourable areas, water supplies
14 of 21
name the four main management strategies for reducing the risk from tectonic hazards
monitoring, prediction, protection, planning
15 of 21
describe the monitoring strategy
scientific equipment detects warning signs of extreme weather
16 of 21
describe the prediction strategy
using historical evidence, scientists can make predictions on when and where hazards may happen
17 of 21
describe the protection strategy
designing buildings that will withstand hazards
18 of 21
describe the planning strategy
with knowing the likely areas that will be affected by tectonic hazards, these areas can be evacuated
