PLATE BONDARIES

PLATE BONDARIES

1. Plate types

   • destructive : oceanic - continetal, oceanic - ocenic
   • contructive: oceanic - oceanic
   • constructive:continetal- continental
     • collision: continental continental

2. Definitions

   • hazard:if it threatens humans life
   • Natural hazard: hazard produced by environmental process
   • Natural disaster:the realisation of a natural hazard on a significant scale + peoples capacity to cope and respond has been overwhelmed
   • Climatic hazard:Extreme weather event caused by atmospheric process
   • geological hazard:hazard caused by process primally tectonic , within earths crust
   • risk : prob of hazardous event occurring + causing damage
   • vulnerability : physical harm

3. crust

   • oceanic
   • continetal

4. Earthqueakes

   • sudden brief period of intense ground shaking
   • richer scale : strength of E according to amount of energy released
     • energy measured in seismograph
   • liquefaction : some soft R that act like liquids because the water pulls the solid particles away
