Plate Tectonics

2. What are Pangea and Godwana?
3. Mostly liquid that makes up the space underneath the upper layer of the earth
5. It is geologically young compared with the continental crust
6. An eruption caused by carbon breaking through the crust
7. The solid layer of Iron and Nickel
10. Two tectonic plates that move away from each other
12. The relatively thick part of the earth's crust which forms the large land masses.
13. The place where two plates meet
15. The plate Australia rests on
19. The very center of the earth
20. The horse shoe shaped ring that contains most of the earth volcanoes and earthquakes
21. The number of major plates

1. The crusts segments that float on the mantle
4. When two plate slide past each other
8. When two plates come together and push together
9. Liquid Iron and Nickel
11. A giant wave that can be caused by an underwater volcano or earthquake
12. The solid outer layer of the earth
14. The super continent that incorporated most of the world modern continents
16. One plate is pushed beneath the other
17. The force on the plate overcomes the friction, that releases energy in waves through the crust
18. The movie based on the theory continental drift
