  1. Plate Tectonics Day3

  2. Review • Plate tectonic Theory http://www.odsn.de/odsn/services/paleomap/animation.html • Surface of earth made of rigid “plates” • Float on asthenosphere and is in constant motion • Explains Drifting continents Mountain building Earthquakes Volcanic activity

  3. Convection Currents and the Mantle

  4. Effects of crustal plate movement!

  5. Constructive ForcesHelp build land There are 3Types of Boundaries Click picture for video http://www.learner.org/interactives/dynamicearth/plate.html

  6. Convergent Boundarieshttp://www.learner.org/interactives/dynamicearth/slip2.html • Boundaries between two plates that are colliding  

  7. Subductionhttp://www.learner.org/interactives/dynamicearth/slip2.htmlSubductionhttp://www.learner.org/interactives/dynamicearth/slip2.html oceanic plates collide with continental plates, and slide beneath them creating trenches. Ex. Mt. St. Helens • http://player.discoveryeducation.com/index.cfm?guidAssetId=489D30FF-EC27-483E-825D-A5FA582A57E4

  8. The ocean floor plunges into deep underwater canyons called deep-ocean trenches. • Subduction takes place in deep-ocean trenches. • Subduction is the process by which the ocean floor sinks beneath a deep-ocean trench and back into the mantle.

  9. The RING of fire Click on picture

  10. Hot Spots hot material rises up through the mantle, heats up the lithosphere and forms a volcano. Once the plate passes over this hotspot, the volcano becomes inactive. Ex. Hawaii http://player.discoveryeducation.com/index.cfm?guidAssetId=C485747E-A115-41D6-9D42-D6FFE6CA3914
