4. the main rock that makes up Earth's crust
6. the percent the crust makes up of Earth's volume
7. the percent the inner and outer core makes up of Earth's volume
8. the layer of Earth that is a dense solid metal ball
11. Sheets of rock that include part of Earth's crust
13. Where plates bump into or slide past each other to cause earthquakes, volcanoes and mountain formations
14. the region of the upper mantle that is hot enough and under enough pressure to deform rocks making them change shape and flow
15. the main mental in Earth's core
16. the parts of Earth's crust that are under the ocean

1. the outermost layer of Earth, composed of rock
2. the parts of Earth's crust that form the continents
3. the layer that plates float on that is molten rock and moves the plates as it flows slowly
5. the rigid outer layer of Earth make up of the solid crust and uppermost part of the mantle
9. the theory that Earth's crust is divided into a number of plates that interact with one another
10. the layer of Earth made of melted: liquid metal
12. the percent the mantle makes up of Earth's volume
17. the second most metal in the Earth's core
