Natural Disasters - Earthquakes, Tsunamis and Volcanoes

5. A volcano that is not presently erupting but that is considered likely to erupt in the future. Is in ‘sleeping’ mode
6. An opening at the earth’s surface from which volcanic material where lava, steam, or gas is emitted
8. A place where a large number of faults are located
10. The point within the earth’s crust where an earthquake begins
11. A large ocean wave
14. A volcano that has had at least one eruption during the past 10,000 years. An active volcano might be erupting or dormant. It could erupt at any moment.
15. Molten material beneath or within the earth's crust
17. When the whole world was connected also called Pangaea.
20. Detached masses of lava shot out by volcanoes, which, as they fall, assume rounded forms like bombshells.
21. A sudden and violent shaking of the ground, sometimes causing great destruction, as a result of movements within the earth's crust or volcanic action
22. When 2 tectonic plates move away from each other
23. When 2 continental plates collide

1. When the volcano explodes/erupts
2. A superheated avalanche consisting of ash, rock and lava that rushes down the mountain –with devastating effects -
3. A scale developed to measure the strength of earthquakes.
4. A small earthquake or tremor that follows a major earthquake
7. Tsunami is a great sea wave produced by a submarine earthquake, volcanic eruption, or large landslide.
9. The molten, fluid rock that issues from a volcano or volcanic vent
12. A magma chamber is a large underground pool of molten rock found beneath the surface of the Earth.
13. A mountain or hill, typically conical, having a crater or vent through which lava, rock fragments, hot vapour, and gas are or have been erupted from the earth's crust.
16. The point on the Earth’s surface directly above the focus
18. When 2 tectonic plates collide and 1 plate slides beneath the other
19. The opening on top of a volcano which lava erupts from
