- plate tectonics and hazards
- destructive plate boundary
- oceanic crust subducted beneath a continental plate or where two oceanic or continental plates collide
- constructive
- oceanic plates moving apart. show/ low magnitude earthquakes, most of which are submarine
- conservative
- plates slide past each other. shallow earthquakes, high magnitude
- earthquake distriubution
- destructive and conservative plate boundaries
- low and high magnitude
- cause secondary hazards
- volcanoes distribution
- constructive and destructive plate boundaries
- where constructive plate boundaries occur on continents volcanoes tend to be more explosive
- 80% occur on destructive plate boundaries
