EQ1: Why are some locations more at risk from Tectonic Hazards?
1.1 - see additional diagram
1.2 - theoretical frameworks that attempt to explain plate movement
1.2b - operation of plate margins
Plate boundary types
Place specific examples per boundary:
converging - Japan 2011 (pacific subducts under Eurasian), conservative - Christchurch eq 2011(pacific and Australian plates), divergent - mid Atlantic ridge.
Convergent (destructive)
Divergent (constructive)
conservative (transform) - plates rub up against each-other with a
Plate types
oceanic
- Thinner and more dense that continental, therefore usually subducts, when two oceanic plates meet there the slightly more dense one will ususaly subduct.
continental
- Ticker and less dense than oceanic meaning it does not subduct, when two continental plate converge neither subduct and fold mountains are formed.
1.2c
1.2a - Key elements of plate tectonics
1.3 - Physical processes explain the causes of tectonic hazards
1.3b - volcanic hazards
Primary Hazards
Gas emissions - water vapour, sulfur dioxide, hydrogen, carbon monoxide.
1.3c - tsunami processes
1.3a - earthquake hazards
