Across
- 2. A type of volcanic eruption that produces lava fountains and gentle lava flows.
- 5. The molten rock beneath Earth’s surface.
- 7. The zone where one plate sinks beneath another into the mantle.
- 8. A volcanic cone with gentle slopes, formed mostly from fluid lava.
- 9. A type of volcanic eruption that produces ash and pyroclastic material.
- 11. Volcanic activity that occurs away from plate boundaries, where magma rises from deep mantle plumes.
- 13. The process by which magma solidifies to form igneous rock.
- 14. A place where plates move apart and magma rises, creating new crust.
Down
- 1. The process of melting mantle rocks due to a drop in pressure.
- 3. The property of magma that describes its resistance to flow.
- 4. Lava that flows quickly because of low viscosity
- 6. Plate boundary where subduction volcanism occurs.
- 10. A volcano type formed by alternating layers of lava and pyroclastic deposits.
- 12. The most common mineral found in igneous rocks, also used in glass-making.
- 13. Small, steep-sided volcano built from pyroclastic fragments.
