Transcript of "Plate tectonics theory"

  1. 1. Plate tectonics theory
  2. 2. <ul><li>What it is? </li></ul><ul><li>It is a theory that describes the large scale motion of the Earth´s lithosphere </li></ul><ul><li>The theory gives an explanation of the tectonic plates that form the surface of the Earth </li></ul><ul><li>The theory builds on the concepts of continental drift </li></ul>
  3. 3. <ul><li>Lithosphere divides into different tectonic plates: </li></ul><ul><li>This are the 12 principals plates </li></ul>
  4. 4. <ul><li>Convergent </li></ul><ul><li>or destructive plate boundary </li></ul><ul><li>This plates can move of different forms </li></ul><ul><li>Transform </li></ul><ul><li>or conservative plate boundary </li></ul><ul><li>Divergent </li></ul><ul><li>or divergent plate boundary </li></ul>
  5. 5. <ul><li>Convergent: two plates move one near to another and collide </li></ul><ul><li>Transform: is a type of fault whose movement is mainly horizontal </li></ul><ul><li>Divergent : two tectonic plates that are moving away from each other </li></ul>
  6. 7. Continental drift <ul><li>It is the movement of the continents </li></ul><ul><li>Until the plate tectonics could not be demonstrated because the movement of the plates explain the continental drift movement. </li></ul>
  7. 8. Seafloor spreading <ul><li>It is the formation of new oceanic crust </li></ul><ul><li>It is also explain thanks to the plate tectonics theory and also help to understand the continental drift </li></ul>
  8. 9. <ul><li>THE END </li></ul>
