geography - hazards Flashcards
whats a natural hazard
a natural process which can cause death, injury or disruption to humans
whats geological hazards?
caused by land and techtonical processes
whats are meteorological hazards
caused by weather and climate
whats vulnerability?
people are more exposed to hazards so the greater possibility that they will be effected
whats HIC
Higher Income Countries
whats magnitude
more severe natural hazards cause greater effects.
what are Earths techtonic plates
inner core, outer core, mantle, crust
destructive margins:
2 plates collide, the ground is foiled and forced up to create mountains or volcanoes
constructive margins:
2 plates move away from each other, magma rises to fill gaps creating a new crust.
what are volcanoes found
found on destructive and constructive plate margins
primary effects from volcanoes:
buildings and roads are destroyed by lava flows
people and animals are injured or killed
crops are damaged
what are secondary effects from volcanoes?
transport network are blocked
people are left homeless
tourism way be distupted - however it could increase ( volcanoes)
immediate responses for volcanoes
evacuate people
provide food and drink
treat injured
long term responses for volcanoes
repair/ rebuild buildings
boost economy
improve monitoring systems
where are earthquake formed
destructive, constructive , conservative margins
how are eathqaukes measured.
magnitude scale
earthquakes primary effects
buildings and bridges are destroyed
people are injured or killed by debris
transport is damaged
