1. Destructive Plate Margins: Features/landforms: Fold mountains Thrust faults Negligible volcanism Regional metamorphism Shallow focus earthquakes (SFQ) Gneiss Thickening of crust Processes: Mountain Building (Orogenesis) Folding Faulting Metamorphism Crustal Thickening Continental-Continental collision

2. Plate Boundaries

3. What are the main differences between Continent-Continent Collision and Oceanic-Oceanic/Oceanic–Continental Collision ? Continent-ContinentOceanic/Continent Negligible volcanismVolcanoes = andesitic rock Shallow EarthquakesDeep and Shallow Earthquakes Extensive granite generation and regional metamorphism Minor granite generation and localised metamorphism Extensive shortening of continental crust – associated thrust faulting Extensive shortening of oceanic crust – localised thrust faulting

4. Conservative Plate Margins: Features/landforms: Shallow focus earthquakes (SFQ) Fault scarps Lateral fault movement Tear/wrench fault (Strike/Slip) Fault zone San Andreas Fault Processes: Lateral plate movement Pressure build up Stress release Fault Displacement

5. Plate Boundaries Why are conservative margins so hazardous to humans ?
