3 Types of Plate Boundary Movements
Sea-Floor Spreading
(New ocean floor is created as the magma fills the gaps created by diverging plates
Mid-Ocean Ridges
SUBDUCTION
(More dense plate will slide below the less dense plate and go back into the mantle: plate destruction)
The Theory of Plate Tectonics
Convection Currents in the Mantle
(hot less dense material rises, cool more dense material falls)
Volcanic Mountain Ranges
Deep Ocean Trench
Island Arc
Wegener/ Continental Drift/ Pangaea
