  1. 5. Rock: forms when hot, molten rock crystallizes and solidifies
  2. 8. Spot: an area of the Earth’s mantle from which hot plumes rise upward, forming volcanoes on the overlying crust.
  3. 9. Plate: a path along the Pacific Ocean characterized by active volcanoes and frequent earthquakes
  4. 10. a portion of the Earth's mantle that flows like molten plastic despite being solid.
  5. 13. A tectonic boundary where two plates are moving toward each other. If the two plates are of equal density, they usually push up against each other
  6. 14. Island: Geologically, a volcanic island is an island of volcanic origin. The term high island can be used to distinguish such islands from low islands, which are formed from sedimentation or the uplifting of coral reefs.
  7. 15. a hot or cold mixture of water and rock fragments that flow quickly down the slopes of a volcano
  8. 16. the sudden release of strain energy in the Earth's crust, resulting in waves of shaking that radiate outwards from the earthquake source.
  9. 18. of Fire: a path along the Pacific Ocean characterized by active volcanoes and frequent earthquakes
  10. 19. a mixture of molten and semi-molten rock found beneath the surface of the Earth.
  11. 20. solid, outer part of Earth, including the brittle upper portion of the mantle and the crust
Down
  1. 1. a mountain or hill, having a crater or vent through which lava, rock fragments, hot vapor, and gas are being or have been erupted from the earth's crust.
  2. 2. The process that occurs when two tectonic plates meet at convergent boundaries, and one of the plates moves under the other one due to gravity and differences in density
  3. 3. Crust: granite
  4. 4. a mixture of rock, mineral, and glass particles expelled from a volcano during a volcanic eruption.
  5. 6. Mountain: formed by oceanic and continental crust in a convergent boundary.
  6. 7. Boundary: The location where two plates meet is called a plate boundary
  7. 11. contain a high-density mix of hot lava blocks, pumice, ash and volcanic gas
  8. 12. molten rock ejected by volcanoes in the form of a liquid
  9. 17. Crust: basalt
