Natural Hazard - ✔✔✔A natural hazard is a natural process which could cause death, injury or
disruption to humans, or destroy proprty or posesions.
Natural disaster - ✔✔✔A natural hzard that has actualy happened
Geological hazards - ✔✔✔Caused by kand and tectonic processes
Meteorological hazards - ✔✔✔Caused by weather and climate
Factors affecting hazard risk - ✔✔✔Urbanisation, poverty, development, climate change
Tectonic plates - ✔✔✔Slabs of the Earth's crust
Continental crust - ✔✔✔thicker and less dense
Oceanic crust - ✔✔✔thinner and more dense
Tectonic plate movement - ✔✔✔caused by convection currents underneath the Earth's crust
Destructive plate - ✔✔✔Two plates moving towards one another, oceanic plate subducts under
continental plate and friction causes melting of oceanic plate, triggers earthquake
Constructive plates - ✔✔✔Two plates move apart, magma forces way along gap and causes
earthquake, erupted lava cools and forms volcano
, Conservative plate - ✔✔✔Two plates moving alongside, friction can send shockwaves causing
earthquakes
Earthquake causes - ✔✔✔two plates 'jerking' past each other
the focus - ✔✔✔the point in the Earth the earthquake starts
Epicentre - ✔✔✔the point on the Earth' surface straight above the focus
Where are volcanoes found - ✔✔✔At destructive and constructive plate marhgins
Where are earthquakes found - ✔✔✔At all three types of plate margin
Earthquake Primary effects - ✔✔✔buildings and bridges collapse
people are injured or killed
Roads are destroyed
Earthquake Secondary effects - ✔✔✔Can trigger landslides, tsunamis = destruction
homeless can die from the cold
Leaking gas can start fires
Earthquake Immediate responses - ✔✔✔Rescue people trapped by collapsed buildings and treat
injured people
Recover dead bodies to prevent spread of disease
