Theory of Plate Tectonics
• Earth’s plates move slowly in different directions
• Divergent– Move away
• Convergent– Move into
• Transverse– Move along

How Fast Do Plates Move???
• Slow plates…– 1-2 mm’s per year
• Fast plates…– 5-6 cm’s per year
• About as fast as your finger nails grow

San Andreas Fault, CA
• L.A. is on the Pacific Plate– Moving NNW at 3 cm’s
per year
• San Francisco is on the N. American Plate– Moving SSE at 2 cm’s
per year
• Now…– 544 km apart
• In 10 million years– Side by side
