Mechanism of Plate Tectonics

• Material in asthenosphere heats and rises• When it cools it moves horizontally and sinks• This movement of material is called

convection cells

Divergent

-Rift Zone-Plates moving apart-Sea Floor created-Mid Ocean Ridges

Convergent

-Subduction Zones-Plates moving toward each other-Seafloor destroyed-Creates trenches & Volcanic Island Arcs

Transform

• Plates move past each other

• Faults are formed

Ring of Fire• Around Pacific Ocean• Greatest quantity of earthquakes/volcanoes• Ring (outer edge of) Pacific Plate is full of faults
