Across
- 4. Formed from oceanic continental convergent plate boundaries.
- 5. Molten rock below the earth's surface near the upper mantle and lower crust.
- 10. A portion of the Earth's mantle that flows like molten plastic despite being solid.
- 13. The layer of granitic, sedimentary, and metamorphic rocks, which form the continents and the areas of shallow seabed close to their shores.
- 14. Formed from oceanic oceanic convergent plate boundaries.
- 15. A hot, chaotic mixture of rock fragments, gas, and ash that travels rapidly away from a volcanic vent or collapsing flow front.
- 16. The solid, outermost layer of Earth, made of the crust and upper mantle.
- 18. The location when two plates converge, and one plate is forced under another.
Down
- 1. Molten rock (magma) erupted from a volcano.
- 2. The location where two plates are being forced together by the convection currents in the earth's mantle.
- 3. A sudden shaking of the ground caused by movement of tectonic plates.
- 6. The solid remanence from fires, explosions, and/or volcanic vents.
- 7. A hot or cold mixture of water and rock fragments that flow quickly down the slopes of a volcano.
- 8. An oceanic tectonic plate that lies beneath the Pacific Ocean.
- 9. A type of rock that forms when molten rock cools and solidifies.
- 11. A path along the Pacific Ocean characterized by active volcanoes and frequent earthquakes.
- 12. The thinner and denser part of earths crust that makes up the ocean floor.
- 17. The location in which two tectonic plates interact through converging, diverging, or transforming.
