  1. Motion Slow Motion on Planet Earth Chapter 1 Section 2

  2. Pieces of Earth’s Crust 12+ major plates Tectonic Plates

  3. “Super-Continent” ~250 million years ago Pangaea

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

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

  6. 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 San Andreas Fault, CA
