3. CONTINENTAL SHELFPANGAEA THEORY OF CONTINENTAL DRIFTTECTONIC PLATES CRUSTMANTLE PLATE BOUNDARIES

4. What Have Scientists Learned About the Earth and its Interior?

5. Earth Pangaea ~ 200 million years ago, all the continents were together as a SUPER-continent…

6. Earth Alfred L. Wegener ~ Created the theory of Continental Drift – the movement of continents due to the floatation of the continents on the core (Magma) in 1912.

7. Continental Drift Alfred Wegener 1900’s Continents were once a single land mass that drifted apart. Continent – large land mass (6 or 7 depending on p.o.v.) Fossils of the same plants and animals are found on different continents Called this supercontinent Pangea, Greek for “all Earth” 245 Million years ago

9. Moon Worship

10. Sun Worship

11. Native American Sun Dance

12. Hawaiian Volcano Worship – Goddess Pele

13. How Plates Move

14. Earth Continental Drift ~ The slow movement of the plates that float on the Magma under the crust.

15. Plate Tectonics Facts Greek – “tectonics” of a builder Pieces of the lithosphere that move around Each plate has a name Fit together like jigsaw puzzles Float on top of the upper-mantle, called the asthenosphere –

16. Sea Floor Spreading

17. Mid Ocean Ridges – underwater mountain chains that run through the Earth’s Basins Magma rises to the surface and solidifies and new crust forms Older Crust is pushed farther away from the ridge

18. Earth Magma ~ Molten (melted) rock inside the Earth – makes up all of the Earth’s outer core.

19. Earth’s Layers The Earth's rocky outer crust solidified billions of years ago, soon after the Earth formed. This crust is not a solid shell; it is broken up into huge, thick plates that drift atop the soft, underlying mantle.

20. The Crust Outermost layer 5 – 100 km thick, depending on where you are.

21. The Mantle Layer of Earth between the crust and the core Contains most of the Earth’s mass Has more magnesium and less aluminum and silicon than the crust Is denser than the crust

24. Earth

25. The Core Below the mantle and to the center of the Earth Believed to be mostly Iron, smaller amounts of Nickel, almost no Oxygen, Silicon, Aluminum, or Magnesium

26. Earth Faults ~ A break in rock along which rock slabs have moved.

27. Earth Convergent Boundary ~ Two plates come together, but one plate is forced underneath the other.

28. Convergent Boundary – Oceanic & Continental

29. Convergent Boundary – Oceanic & Oceanic

30. Convergent Boundary – Indian and Eurasian Plates

31. Ausable Chasm – Adirondack Mts. NY

32. Elephant Head – Asuable Chasm

33. Earth Divergent Boundary ~ Plates move away from each other.

34. Divergent Boundary - Oceanic

35. Divergent Boundary – Iceland

36. Divergent Boundary – Arabian and African Plates

37. Earth Transform-Fault Boundary ~ Plates move past one another.

38. Transform Boundary – San Andreas Fault

39. Can You Answer These? What are the three main layers of the Earth What was Pangea? What is Sea-Floor spreading? Name the three different types of plate boundaries and one location on Earth for each one.
