7. The hard outer layer the earth
11. Extremely hot molten rock that is found beneath earth's surface
12. Divergent Plates pull apart creating new crust
13. Something like a rock that has been changed by exposure to heat, pressure and more.
16. Tectonics The scientific theory that the Earth's outer shell is broken into large plates
17. an area of unusually hot mantle material located deep within the Earth

8. Process of two or more things moving towards each other forming a whole
9. The act of pressing something into a smaller space or putting pressure on it from different sides until it gets smaller.
10. Spreading The geological process where new oceanic crust is formed at mid ocean ridges as tectonic plates pull apart.
14. Molten rock that erupts and flows on earth's surface
15. The center innermost layer of the planet
18. Opening in the Earth's crust where magma erupts from beneath the surface forming a mountain shape.
