Across
- 2. An opening in the Earth's surface, usually found in a mountain, the opening allows gas, hot magma and ash to escape from beneath the Earth's crust
- 4. The outermost layer of our planet
- 6. Are places where two plates move away from each other
- 8. This mostly solid, dense layer makes up the majority of Earth’s interior
- 10. A landform that rises high above the surrounding terrain in a limited area.
- 11. Earth’s final layer, the inner core is also composed mostly of iron and nickel
- 12. Hot, liquefied rock that flows from a volcano or other opening in the surface of Earth
- 13. Molten, or hot liquefied, rock located deep below the Earth's surface
- 14. The liquid layer, composed of primarily iron-nickel
- 15. A scientific theory that explains how major landforms are created as a result of Earth's subterranean movements.
Down
- 1. are places where two plates meet
- 3. A place where two side-by-side plates grind past each other
- 5. Is the circular motion that occurs when warmer material rises and replaces cooler material.
- 7. The solid, outer layers of Earth
- 9. Located beneath the Lithosphere, this layer within the Earth’s Mantle that is composed of denser and weaker material that acts like a lubricant, allowing for the tectonic plates to move
