  1. Plate Boundaries By: Miss Shrestha & Miss Morris

  2. Plate Boundaries • Sliding Boundaries • Convergent Boundaries • Divergent Boundaries

  3. Plates sliding sideways against each other. Plates rubbing together form earthquakes. Example: San Andreas Fault in California. Sliding Boundaries

  4. Convergent Boundaries • Plates pushing together. • Plates pushing or colliding together form earthquake and volcanoes.

  5. Convergent Boundaries • Plates push together to form mountains. • Example: Rocky and Himalayas Mountains. • When continental and oceanic plates collide the thinner plate slides under the other plate. This is called subduction.

  6. Divergent Boundaries • Plates pulling apart. • Plates separate to form volcanoes and minor earthquakes. • Example: Mid Atlantic ridge

  7. Plate Boundaries 1. Click on the website below. 2. Click on the next view bottom at the lower right hand side to watch other plate movements. http://www.wwnorton.com/college/geo/egeo/flash/2_6.swf

  8. Mountain Building • New mountains form when plates pull apart magma push out from below and the lava cools and turns to rock.

  9. Mountain Building • When plates push together, one plate is pushed beneath the other one, and this creates mountains. Visit the following website: http://www.classzone.com/books/earth_science/terc/content/visualizations/es1105/es1105page01.cfm?chapter_no=visualization

  10. Fault Block Mountains • Form when masses of rock move upor down along a fault.

  11. Folded Mountains • Form when two tectonic plates collide.

  12. Dome Mountains • Form when the surface is lifted up by magma, forming a bulge.
