Across
- 5. Rising column of hot mantle material
- 8. Underground reservoir where magma accumulates
- 9. The solid outer layer above the mantle
- 11. Molten rock formed beneath Earth's surface
- 12. Process of solid rock turning into liquid magma
- 14. Plate sinking into mantle, triggering magma formation
Down
- 1. Mantle movement that transports heat and material upward
- 2. Substances like water that help melt mantle rock
- 3. Melting caused by reduced pressure at divergent boundaries
- 4. Energy source that initiates rock melting
- 5. Physical force that affects melting point of mantle rocks
- 6. Melting triggered by water and volatiles lowering the melting point
- 7. Increases with depth, helping rocks melt into magma
- 10. Earth's layer where most magma originates
- 13. Zone where tectonic plates diverge and magma forms
