  1. 1. Continental-Continental Convergent Done by Li Wang, Jasmine Lin, Park Byeong Joo, Clara Che Wei Peh
  2. 2. Done by Li Wang, Jasmine Lin, Park Byeong Joo, Clara Che Wei Peh <ul><li>Content </li></ul><ul><li>What is continental- continental convergent? </li></ul><ul><li>Resultant Landforms- Fold Mountains </li></ul><ul><li>Types of Folds </li></ul><ul><li>Examples </li></ul><ul><li>References </li></ul>
  3. 3. What is convergent?
  4. 4. <ul><li>The movement of two plates moving together and colliding with one another. The denser plate will subduct under the light plate, and if they are too light to subduct under, they converge and form a complex mountain range with great height. </li></ul>
  5. 5. What is continental-continental convergent?
  6. 6. <ul><li>This occurs when two continental plates are pushing against each other, and produces colossal bending and folding of the plate at the boundaries, which makes it likely to take shape of a fold mountain range. An example would be the Himalayas. </li></ul>

  9. 9. Fold Mountains- Formation
  10. 10. When an area of sea separates two plates, sediments will settle onto the sea floor and become sedimentary rocks. When the plates move towards each other, the layers of sedimentary rock become crumpled and folded, which makes them fold mountains.
  11. 11. syncline anticline Where the rocks are folded upwards, they are called anticlines. Where the rocks are folded downwards, they are called synclines.
  12. 12. Anticline
  13. 13. Syncline
  14. 14. Monocline
  15. 15. Types of Folds
  16. 16.
  17. 17. Symmetrical Folds
  18. 18. Folds may be symmetrical or asymmetrical. In a symmetrical fold , the axial plane is vertical and the sides dip symmetrically from the axis. A symmetrical fold is one in which the axial plane is vertical. 
  19. 19.
  20. 20. Asymmetrical Folds
  21. 21. In an asymmetrical fold, the axial plane is tilted from the vertical and inclined with one limb dipping more steeply than the other. 
  22. 22.
  23. 23. Isoclinal Folds
  24. 24. A fold in sedimentary rocks where the axial surface and limbs slope in the same direction and at approximately the same angle.
  25. 25. Overturned Folds
  26. 26. A fold that’s axial plane’s tilted and beds may dip in same direction of both sides of the axial plane, resulting in one of limbs being rotated through an angle of at least 90 degrees.
  27. 27.
  28. 28. Recumbant Folds
  29. 29. A plate's axial plate is horizontal, so one of the limbs is completely covered. it is the extreme version of the over turned fold but rotated more then 90 degrees.
  30. 30.
  31. 31. Chevron Folds
  32. 32. A very abrupt hinge with long straight limbs which ranges from 10 to 70 degrees.
  33. 33. Where are fold mountains found?
  34. 34. Himalayas
  35. 35. The Alps
  36. 36. Andes
  37. 37. Rockies
  38. 38. Urals
  39. 39. Notes Axial Plane: an imaginary plane surface that divides a fold symmetrically Fold Axis: a line drawn along the points of maximum curvature of a layer of a fold Plunge: the angle between the horizontal plane and the fold axis
