3.1.1.1 Natural hazards Flashcards
Define a natural hazard
It’s a natural process which could cause death, injury or disruption to humans or destroy property/possessions
Define a natural disaster
Natural disaster is a natural hazard that has happened
Name the two main types of natural hazards
Geological hazards & meteorological hazards
What are meteorological hazards caused by?
Caused by weather and climate
What are geological hazards caused by?
Caused by land and tectonic processes
Name 2 examples of a geological hazard
Volcanoes, earthquakes, landslides and avalanches
Name 2 examples of a meteorological hazard
Tropical storms, Climate change & extreme weather
Name 3 factors that affect the hazard risk from natural hazards
Vulnerability, Capacity to Cope & Nature of Natural Hazard
Explain how vulnerability affects the hazard risk from natural hazards
More people in areas exposed to natural hazards = greater probability they’ll be affected by a natural hazard
Explain how the capacity to cope affects the hazard risk from natural hazards
The better a population can cope with extreme event = lowers threat
Explain how the nature of a natural hazard affects the hazard risk from natural hazards
Type - hazard risk from some hazards is greater than others
Frequency - some natural hazards occur more often than others = increasing hazard risk
Magnitude - more severe natural hazards cause greater effects than less severe natural hazards
