Presentation Transcript

  1. The Earth The earth rotates on its axis from west to east, causing places in the east to see the sun first.

  2. Plate Tectonics

  3. How Plates Move Convergence Zone Plates move towards each other in a zone of convergence resulting in fold mountains or subduction zones.

  4. Divergence Zone Plates move away from each other in a zone of divergence resulting in deep sea trenches and rift valleys

  5. Transform or neutral Plates Plates move past each other, grating, grinding and breaking apart resulting in features such as transform faults

  6. Continental Drift 200 million years ago the earth was divided into 1 mass of land called pangea and 1 body of water called panthalassa. Over time pangea started to break up and drift apart, resulting in a process known as continental drift

  7. Subduction zone

  8. Ocean Floor When plates move, there are a few things that occur along the ocean floor. Divergence causes sea floor spreading and convergence results in ridges

  9. The Earth’s Plates The earth is divided into tectonic plates. There are 7 major plates and 7 minor plates. The Indian and Austrailian plates make up the Indo-austrailian plate. The plates are further grouped according to their crust as oceanic or continental.
