J. TUZO WILSON

• He said that the lithoshere is broken into separte sections called plates.

HOW PLATES MOVE

• The theory that pieces of earth's lithosphere are in constant motion , driven by convection currents in the mantle
• It explains the formation , movement ,and subduction of earth's plates

PLATE BOUNDARIES

• Diergent
• Convergent
• Transforms

DEF. OF PLATE BOUDARIES

• Divergent : is a place where 2 plates move apart or diverge
• Convergent:when 2plates collides they converge
• Transform:is a place where 2 plates slip past each other

Pangea drifted together 260 million years ago

225 million it started to break up
