natural hazards and plate margins Flashcards
what are natural hazards
extreme hazard events which can cause extreme damage and destruction to property and death
what can human activities influence on natural hazards
frequency and severity
difference between tectonic and climatic hazards
tectonic occurs when friction causes the crust to become stuck and tension builds up, when released earthquakes are caused
climatic occurs when a region has certain weather conditions
examples of climatic and tectonic hazards (3)
volcanic eruptions, tsunamis, avalanches
droughts, tropical storms, tornadoes
difference with short and long term effects in developed and developing countries
death rate lower, but higher economic cost in developed vice versa
developing countries may be slower to repair damaged infrastructure, decreasing tourism and valuable income
what increases risks of hazards
pop growth, urbanisation and changes to natural environment
what makes up the earths structure
inner core, outer core, mantle, crust
