Across
- 3. An oceanic plate which also happens to be the largest plate on Earth
- 6. Either created by erosion or by subduction
- 10. The remains of dead animals and plants after long periods of time
- 11. Deposit of dead plants compressed and heated over the course of millions of years
- 13. A group of islands scattered across a body of water
- 14. One of the main metals in the Earth's core
- 15. The innermost layer of the Earth, comprised of mostly iron and nickel
- 16. Beneath the crust and made mostly of rocks and mineral
- 18. The moving of Earth's magma, making tectonic plates too move

Down
- 1. Lie along boundaries of tectonic plates where earthquakes occur frequently
- 2. One of the main metals in the Earth's core
- 3. Able to be shaped and molded easily
- 4. The state of matter where matter is less tightly packed than a solid but not gaseous
- 5. A shell mostly made up of solid rocks and minerals
- 7. Occur along divergent plate boundaries, where new ocean floor is made
- 8. The state of matter where matter is most tightly packed
- 9. At the border of divergent plates, and can occur both on land and under water
- 12. Occurs when two convergent plates collide
- 17. The outer part of the Earth containing the crust and outer mantle
