Where are tectonic hazards (distribution) |
Plate margins (tectonic plates) often on the edges of continents, occur in lines, big cluster along the ring of fire, Pacific plate |
|

|
|
What does a constructive plate boundary do and what forms? |
Pull apart due to convection currents, volcanoes and earthquakes happen. Iceland is an example |
|
|
|
What does a destructive plate boundary do, and what forms? |
Played push into each other, oceanic crust sinks below continental, volcanoes and earthquakes and tsunamis happen; fold mountains and ocean trenches form |
|
|
|
What do conservative plate boundary’s do and what happens there |
Push past each other or move in same direction at different speeds, only earthquakes happen here. E.g San Andreas fault |
|
|
|
Earthquake causes |
Friction builds between plates (at all types of plate boundaries), tension builds as plates move and energy is released in shockwaves |
|
|
|
3 Primary Effects of earthquakes |
Buildings collapse Deaths Injuries Roads/railways/airports damaged Communities effected (electricity, water, etc) |
|
|
|
3 secondary effects of an earthquake |
Landslides Tsunamis Gas leaks Fires Disease Expensive repairs |
