Across
- 2. A crack or fracture in the Earth's crust associated with the movement of plates
- 6. The dense layer of hot, semisolid rock located directly below the crust
- 7. A boundary where two plates slide horizontally past one another in opposite directions
- 8. A plate boundary where two plates push toward each other or collide, often forming mountains
- 9. Circular currents in the mantle caused by heating and cooling that act as the "engine" for plate movement
- 10. The scientist who noticed continents fit like puzzle pieces and proposed the theory of Continental Drift
- 11. The process where a denser oceanic plate dived underneath a continental plate and melts
Down
- 1. The Greek word for "all the earth"; the original supercontinent that existed 250 million years ago
- 3. A deep valley in the ocean floor created at a subduction zone
- 4. The rigid outer part of Earth, consisting of the crust and the very top of the mantle
- 5. Molten rock found below the ground that oozes up to fill gaps between plates
- 9. The Earth's "skin"; its hard, rigid, and thinnest outermost layer
- 12. A plate boundary where plates move apart or divide, creating new ocean floor
