This report is about the convection current and the processes involved in this phenomena. This also includes a jingle (with lyrics) on the first part so that people could remember what theories are related to convection current and most importantly how it happends.

Convection Current

  1. 1. CONVECTION CURRENT Joshua T. Padua, Happy Nezza B. Aranjuez, Mariah Cyrielle T. Cabantud, Shaica S. Cordez, Liana Camille D. Cruz, Anna Stephanie K. Fernando, Anne Kristine S. Gallo, Maria Angelica S. Reyes
  2. 2. “LAVA”
  3. 3. A long long time ago There was this continent Pangaea was its name In the middle of the sea
  4. 4. This was set in 1912 By Alfred Wegener In Greek it means “All Earth” And it’s the Continental Drift
  5. 5. Although he showed his proofs Jigsaw puzzle, fossils, rocks Coal deposits too But something’s missing still
  6. 6. I have a dream I hope will come true That Continental Drift Will soon be approved
  7. 7. I wish that the Earth, sea the sky up above-a Will help, me to know a lot-a
  8. 8. Years of spending all along With Harry Hess and Robert Dietz Now, with Seafloor Spreading They explained the world
  9. 9. They compared the age and depth Of the rocks and sediments at the ridge Of plates, and concluded That Earth’s plates do move
  10. 10. Now magnetic reversals happen To strengthen up the point of view Of rocks, varying In directions and the age
  11. 11. I have a dream I hope will come true That Seafloor Spreading Will be approved
  12. 12. I wish that the Earth, sea the sky up above-a Will help, me to know a lot-a
  13. 13. Now the people know these two Which will lead to our real topic, which is the process of Convection Current
  14. 14. I have a dream I hope will come true That Convection Current Will be approved
  15. 15. We thank the Earth, sea and the sky we thank too Now I know that it’s true Now I know that it’s true Now I know that it’s true
  16. 16. CONVECTION CURRENT process by which less dense material rises and more dense material sinks
  17. 17. Solid mantle??
  18. 18. CAUSES OF CONVECTION CURRENTS 1. Pressure and Temperature 2. Density 3. Cooling 4. Earth’s rotation
  19. 19. Although mantle convection is so slow, over millions of years this velocity amounts to considerable travel distances for the moving material
  20. 20. PLATE TECTONICS
  21. 21. EFFECTS OF CONVECTION CURRENTS TO OTHER SUBSYSTEMS
  22. 22. Direct
  23. 23. movements of plates forms boundaries such as convergent, divergent and transform fault GEOSPHERE
  24. 24. Himalayan Mountain was formed as a result of the collision between the Indian and Eurasian plate.
  25. 25. main way heat from Earth’s interior is transported to its surface, and this heat escapes principally through mid-ocean ridges HYDROSPHERE
  26. 26. escaping heat along these ridges causes hot water to circulate through the crust in a “hydrothermal system” HYDROSPHERE
  27. 27. gases and dust particles thrown into the atmosphere during volcanic eruptions have influences on climate ATMOSPHERE
  28. 28. living things living near a volcano or fault lines experience great danger BIOSPHERE
  29. 29. Indirect
  30. 30. ATMOSPHERE TO BIOSPHERE
  31. 31. HYDROSPHERE TO BIOSPHERE
  32. 32. GEOSPHERE TO BIOSPHERE
