Across
- 1. Heat transfers by movement of currents in liquids and gases; caused by differences in temperature and density
- 4. Plate Boundary that spreads apart or goes opposite directions
- 6. 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.
- 8. A shaking of a part of the earth's surface that often causes great damage
- 9. Plate Boundary that come together
- 11. 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)
- 14. Plate Boundary that rub together, they do not go up in elevation but slide opposite directions
- 16. Heat transfers through space
- 17. Evidence of glaciers on the equator and tropical forests in the Arctic Ocean
- 19. Wegener German scientist who proposed (in 1915) that the continents were slowly drifting apart
- 20. Hess American geologist, was a scientist who studied mid-ocean ridges
Down
- 1. Heat transfers by touching (within a material or between materials)
- 2. The mantle just below the lithosphere
- 3. 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
- 5. Wegener said that all of the continents were once joined together in a supercontinent
- 7. An area of land that rises very high above the land around it and that is higher than a hill
- 10. Science that deals with the history of the earth and its life especially as recorded in rocks
- 12. in Continents The coastline of Africa and South America looked like they fit together
- 13. Molten rock from a volcanic flowing on Earth's surface
- 15. 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
- 18. Molten rock beneath earth's surface
