Continental Drift

5. The type of crust that is thicker and makes the continents.
8. After WW2 this man provided more evidence for continental drift, this time for the mechanism behind it.
9. This layer of the Earth is the heat source underneath the mantle, which causes convection.
11. The meteorologist who first proposed the theory that the continents drifted.
12. The type of crust found under the ocean. It is the seafloor.
13. The process that creates new sea floor as plates move away from each other at the mid-ocean ridges.
15. Continents fit together like one of these when they are cut out and moved together.

1. Alfred Wegener noticed that the coast of South America seemed to fit into the coast of this continent, just like a jigsaw puzzle.
2. Another piece of evidence for continental drift - these large things also line up nicely when continents are pieced together.
3. A word starting with S that could describe the movement of convection.
4. What happens to temperature as you go deeper in the Earth?
6. Section of the Earth below the crust.
7. Alfred noticed that these were the same on different continents even though the continents were separated by oceans
10. The force in the mantle that causes tectonic plates to move.
14. When the bottom of the mantle is heated it begins to what?
