4. Tectonics The scientific theory that the Earth's outer shell is broken into large plates
6. A zone of fractures in the Earth's crust where tectonic plates have moved
10. Process by which heat is transferred by movement of a heated fluid such as air or water.
12. An event where 2 or more objects come into violent contact or crash with each other
14. A string of volcanoes or earthquakes around the Pacific Ocean
15. Divergent Plates pull apart creating new crust
18. A supercontinent that existed on earths hundred of millions of years ago
20. an area of unusually hot mantle material located deep within the Earth

1. Molten rock that erupts and flows on earth's surface
2. Drift A theory that Earths continent have drifted across the planets surface
3. Something like a rock that has been changed by exposure to heat, pressure and more.
5. A geological process where one tectonic plate slides and sinks beneath each other
7. The act of pressing something into a smaller space or putting pressure on it from different sides until it gets smaller.
8. The center innermost layer of the planet
9. Process of two or more things moving towards each other forming a whole
11. Sudden violent shaking of the ground.
13. Opening in the Earth's crust where magma erupts from beneath the surface forming a mountain shape.
16. Spreading The geological process where new oceanic crust is formed at mid ocean ridges as tectonic plates pull apart.
17. Extremely hot molten rock that is found beneath earth's surface
19. The hard outer layer the earth
