TRANSCRIPT

  • Slide 1
  • A MAP OF EARTH'S TECTONIC PLATES
  • Slide 2
  • Slide 3
  • DIVERGENT PLATE BOUNDARY: - Plates move away from the mid-ocean ridge due to the direction the convection currents in the asthenosphere are traveling. -Sea-floor spreading happens here.
  • Slide 4
  • Slide 5
  • THE RED SEA: - This is an example of a Divergent Plate Boundary. -The African and Arabian plates are moving in opposite directions away from the mid-ocean ridge that runs through the center of this sea. -The Red Sea gets slightly larger each year due to the sea-floor spreading that happens here. `
  • Slide 6
  • CONVERGENT PLATE BOUNDARIES 1. Oceanic-Oceanic 2. Continental-Continental 3. Oceanic-Continental Questions to think about: -What happens at each of these types of convergent boundaries? -What features will you find on the Earth's surface at each of these 3 convergent boundaries?
  • Slide 7
  • Oceanic-Oceanic Convergent Plate Boundaries The denser oceanic crust subducts forming a trench above the subduction zone.
  • Slide 8
  • CONTINENT-CONTINENT CONVERGENT PLATE BOUNDARY Continental crust will not subduct, results in the formation of a mountain range. Mountain Range
  • Slide 9
  • CONTINENT-CONTINENT CONVERGENT PLATE BOUNDARY
  • Slide 10
  • - When an oceanic plate converges with continental, the denser oceanic plate subducts. - This forms a trench above the subduction zone that runs parallel to the coastline and a volcanic mountain range along the continent's coast.
  • Slide 11
  • Oceanic-Continental Convergent Plate Boundary When an oceanic plate converges with continental, the denser oceanic plate subducts. This forms a trench above the subduction zone in the ocean adjacent to the coastline and a mountain range along the continent's coast. The Andes Mountain Range The Peru-Chile Trench
  • Slide 12
  • TRANSFORM PLATE BOUNDARY
  • Slide 13
  • THE SAN ANDREAS FAULT - This is an example of a transform plate boundary. -The 2 sides of this boundary move passed each other in opposite-horizontal directions. `
  • Slide 14
  • THE SAN ANDREAS FAULT - This is an example of a transform plate boundary. -The 2 sides of this boundary move passed each other in opposite-horizontal directions.
