Plate Boundries
Destructive - Where two plates collide and one plate flows beneath the other – subduction.
- Earthquakes and volcanoes occur here
- E.g.: Nazca Plate and South American Plate
Constructive - Rising convection currents pull crust apart forming volcanic ridge - Mid-Atlantic Ridge
- E.g.: Eurasian and North American Plates
Conservative - Two plates slide past each other
- Earthquakes occur here
- E.g.: San Andreas Fault, California
Collision - Two continental plates collide and the two plates buckle
- Many earthquakes occur here
- E.g.: Indo-Australian and Eurasian plates
