Tectonic Process And Hazards Flashcards
What is Plate tectonics theory?
The theory that tectonic plates float and move on the mantle causing continental drift and subduction.
Types of plate boundaries?
Divergent: plates move apart (east Africa rift)
Convergent: plates move towards each other (Himalayan mountains)
Transform: plates slide past each other (San Andreas fault)
What are Subduction Zones
Areas where one tectonic plate is forced bellow another (Andes mountains)
Tsunami case study ?
2004 Boxing Day tsunami
What is a Prediction method of tectonic hazards?
Seismic monitoring
