3. the rigid outer part of the earth, consisting of the crust and upper mantle
6. a horseshoe-shaped region around the Pacific Ocean that experiences frequent earthquakes and volcanic eruptions
7. a small area or region with a relatively hot temperature in comparison to its surroundings.
11. any sudden shaking of the ground caused by the passage of seismic waves through Earth's rocks
14. the relatively thick part of the earth's crust that forms the large landmasses
15. Boundary- The location where two plates meet
16. coming closer together
18. the sideways and downward movement of the edge of a plate of the earth's crust into the mantle beneath another plate.
19. hot molten or semifluid rock erupted from a volcano or fissure, or solid rock resulting from cooling of this
20. the powdery residue left after the burning of a substance

1. an island of volcanic origin
2. oceanic tectonic plate that lies beneath the Pacific Ocean
4. form when hot, molten rock crystallizes and solidifies.
5. the upper layer of the earth's mantle, below the lithosphere, in which there is relatively low resistance to plastic flow and convection is thought to occur.
8. a dense, destructive mass of very hot ash, lava fragments, and gases ejected explosively from a volcano and typically flowing downslope at great speed.
9. the relatively thin part of the earth's crust which underlies the ocean basins
10. hot fluid or semifluid material below or within the earth's crust from which lava and other igneous rock is formed on cooling.
12. -a mountain or hill, typically conical, 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.
13. a destructive mudflow on the slopes of a volcano.
17. a special class of mountains. A volcano is a vent or opening through which magma, ash, gases, and water vapor are ejected out
