3 types of plate boundaries by Omar Dabdoub

Divergent boundary: Ocean-Ocean (Seafloor spreading)

Convection currents pull 2 ocean plates apart hot less dense magma rises in the middle, coolest hardens pushing the old seafloor out.

Ex: Mid-Ocean Ridge

Convection currents push 2 continental plates apart magma rises in the middle cools hardens then sinks forming a valley

Ex: Rift valleys

C-C more plates ocean or continental 2 in the opposite direction or the same direction at different speeds

Ex: Earthquake

Convection currents cause denser ocean plates to dive under continental plate ocean melt forms magma and magma rises forming a volcano

Ex: Mountains, Ocean Trenches, Volcanos

Convection currents cause 2 ocean plates to move towards each other plates are always older colder and dense and dive under the other plate.

Ex: Ocean Trenches Volcanic Islands

CC causes 2 continental plates to move toward each other plates are the same density there no subduction occurs and the 2 plates crumble up

Ex: Mountains
