Across
- 2. sea wave ,a series of large ocean waves generated by a significant disturbance of the sea floor, most often an earthquake.
- 5. molten rock that has erupted onto the Earth's surface from a volcano.
- 7. Any opening at the Earth's surface through which magma erupts or volcanic gases are emitted.
- 8. a great sea wave produced especially by an earthquake or volcanic eruption under the sea
- 11. a slight earthquake
- 12. volcano, have a recent history of eruptions; they are likely to erupt again
- 14. a smaller earthquake following the main shock of a large earthquake.
- 16. an earthquake
- 18. a fine particulate material, resembling flour, produced during explosive volcanic eruptions
- 19. move up and down or from side to side with rapid, forceful, jerky movements.
Down
- 1. forms when magma rises to the Earth's surface through a rift, which is a linear fissure or fracture in the crust.
- 3. eruption, a violent and energetic event where magma and gas are forcefully expelled from a vent, often resulting in the formation of ash clouds, pyroclastic flows, and the dispersal of volcanic debris.
- 4. ,a violent shaking or disturbance of the earth
- 6. a volcano that forms over a stationary area of unusually hot magma deep within the Earth's mantle, called a mantle plume
- 9. a violent or sudden change or disruption to something.
- 10. wave ,a series of powerful ocean waves (or waves in any large body of water) caused by the displacement of a large volume of water.
- 13. a sudden violent shaking of the ground, typically causing great destruction, as a result of movements within the earth's crust or volcanic action.
- 15. a bowl-shaped depression, often found at the summit of a volcano, formed by volcanic activity
- 17. wave, an exceptionally large ocean wave, especially one caused by an underwater earthquake or volcanic eruption.
