Across
- 4. Consists of Earth's crust and upper mantle and is where plate tectonics occur
- 6. The study of the chemistry, crystal structure, and physical properties of minerals
- 8. One plate sinks beneath the other
- 10. The study of life on earth reflected in the fossil record
- 14. Tectonic plate boundary where crust is destroyed as plates move toward each other
- 15. Thinnest layer of the Earth, often described as rigid and fragile, while containing a majority of the elements found on Earth (>90% silicon and oxygen)
Down
- 1. The study of earthquakes
- 2. Tectonic plate boundary where crust is neither produced nor destroyed as plates slide past each other
- 3. Tectonic plate boundary where new crust is formed as plates move apart from each other
- 5. Thickest layer of the Earth made of molten rock, described as plasticity, and comprises of mainly the following elements: silicon, oxygen, and magnesium
- 7. Within the upper mantle and is the weak, easily deformed layer of the Earth that the tectonic plates slide over
- 9. Solid, dense ball made up of iron and nickel
- 11. The study of the universe beyond Earth's atmosphere (a.k.a. space, the final frontier)
- 12. The study of the history of Earth and its life recorded in rocks
- 13. Liquid molten rock, containing mostly iron and nickel
