Types Of Volcanoes Powerpoing 2

  1. 1. <ul><li>Lets Review…… </li></ul>
  2. 2. Magma Chamber <ul><li>Lies inside the earth. Stores hot, melted rock called magma. </li></ul>
  3. 3. Central Vent <ul><li>Opening at the top of the volcano in which lava, pieces of rock and other materials pour out of. </li></ul>
  4. 4. Conduit <ul><li>Vertical channel or pipe in which magma moves up before it reaches the surface of the earth. </li></ul>
  5. 5. Crater <ul><li>Bowl-shaped hole which forms at the top of the volcano. </li></ul>
  6. 6. Lava Flow <ul><li>Lava is very hot when it erupts out of a volcano. The lava flows down the sides of the volcano. As it moves, the lava cools and hardens. </li></ul>
  7. 7. The Three Major Types of Volcanoes
  8. 8. Volcano number 1
  9. 9. Volcano number 2
  10. 10. Volcano number 3
  11. 11. <ul><li>Volcanoes are classified by: </li></ul><ul><ul><li>Their shape </li></ul></ul><ul><ul><li>The way they erupt </li></ul></ul><ul><ul><li>The materials from which they are formed </li></ul></ul>
  12. 12. <ul><li>There are three main types of volcanoes that we need to learn about. They are: </li></ul><ul><ul><li>Cinder Cone Volcanoes </li></ul></ul><ul><ul><li>Shield Volcanoes </li></ul></ul><ul><ul><li>Composite Volcanoes </li></ul></ul>
  13. 13. Cinder Cone Volcanoes <ul><li>Cone shaped with very steep sides </li></ul><ul><li>Relatively small-usually less than 300m (984ft) </li></ul><ul><li>Built from lava fragments called cinders </li></ul><ul><li>Very little lava </li></ul><ul><li>Ex: Paricutin in Mexico and Stromboli in Italy </li></ul>
  14. 14. Shield Volcanoes <ul><li>Looks like a shield </li></ul><ul><li>Large mountains with gentle slopes </li></ul><ul><li>Formed from lava that flows slowly from a crack in the Earth’s curst </li></ul><ul><li>Ex: Mauna Loa located in Hawaii is the largest volcano on Earth </li></ul>
  15. 15. Composite Volcanoes <ul><li>Looks like and upside-down V and has steep sides </li></ul><ul><li>Formed from the most explosive volcanoes </li></ul><ul><li>Eruptions usually occur without warning and can be very destructive </li></ul><ul><li>Layers of rock and lava </li></ul><ul><li>Ex: Mount Fuji which is located in Japan </li></ul>
  16. 16. What type of volcano am I? <ul><li>I have large mountains with gentle slopes </li></ul><ul><li>Answer: Shield Volcano </li></ul><ul><li>I am built from lava fragments called cinders </li></ul><ul><li>Answer: Cinder Cone Volcano </li></ul>
  17. 17. What type of volcano am I? <ul><li>I am made up of layers of rock and lava </li></ul><ul><li>Answer: Cinder Cone Volcano </li></ul><ul><li>I produce very little magma </li></ul><ul><li>Answer: Cinder Cone Volcano </li></ul>
  18. 18. What type of volcano am I? <ul><li>I look like an upside-down V </li></ul><ul><li>Answer: Composite Volcano </li></ul><ul><li>I erupt usually without warning and can be very destructive </li></ul><ul><li>Answer: Composite Volcano </li></ul>
  19. 19. What type of volcano am I? <ul><li>I am relatively small in size-usually less than 300m </li></ul><ul><li>Answer: Cinder Cone Volcano </li></ul><ul><li>Formed from lava that flows slowly from a crack in the Earth’s crust </li></ul><ul><li>Answer: Shield Volcano </li></ul>
  20. 20. What type of volcano am I?

  1. A particular slide catching your eye?

    Clipping is a handy way to collect important slides you want to go back to later.
