Earth's Structure

3. the main rock that makes up Earth's crust
4. the parts of Earth's crust that are under the ocean
6. the percent the inner and outer core makes up of Earth's volume
8. the rigid outer layer of Earth make up of the solid crust and uppermost part of the mantle
10. Where plates bump into or slide past each other to cause earthquakes, volcanoes and mountain formations
13. the theory that Earth's crust is divided into a number of plates that interact with one another
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 second most metal in the Earth's core
16. the percent the mantle makes up of Earth's volume

1. the outermost layer of Earth, composed of rock
2. the layer that plates float on that is molten rock and moves the plates as it flows slowly
4. the layer of Earth made of melted: liquid metal
5. the parts of Earth's crust that form the continents
7. the layer of Earth that is a dense solid metal ball
9. the main mental in Earth's core
11. the percent the crust makes up of Earth's volume
12. Sheets of rock that include part of Earth's crust
