Plate Tectonics

2. Heat transfers through space
5. Wegener said that all of the continents were once joined together in a supercontinent
7. Tectonics A scientific theory that the Earth's surface is made of very large sections that move very slowly; also the movements of the large sections that form the Earth's surface
8. spreading The divergence at mid-ocean ridges of the tectonic plates underlying the oceans that is due to upwelling from the earth's interior of magma which solidifies and adds to the spreading plates
9. A shaking of a part of the earth's surface that often causes great damage
10. Heat transfers by touching (within a material or between materials)
12. Heat transfers by movement of currents in liquids and gases; caused by differences in temperature and density
13. Wegener German scientist who proposed (in 1915) that the continents were slowly drifting apart
15. Evidence that fossils of the same plants and animals are found today on widely separated continents (including Africa, South America, Antarctica, Australia, and Asia - India)
17. Science that deals with the history of the earth and its life especially as recorded in rocks
18. An area of land that rises very high above the land around it and that is higher than a hill
20. Plate Boundary that rub together, they do not go up in elevation but slide opposite directions

1. Plate Boundary that spreads apart or goes opposite directions
3. Molten rock beneath earth's surface
4. Hess American geologist, was a scientist who studied mid-ocean ridges
6. The mantle just below the lithosphere
11. Evidence of glaciers on the equator and tropical forests in the Arctic Ocean
12. Plate Boundary that come together
14. a series of water waves caused by the displacement of a large volume of a body of water, generally an ocean or a large lake.
16. in Continents The coastline of Africa and South America looked like they fit together
19. Molten rock from a volcanic flowing on Earth's surface
