Natural disaster

3. An overflow of a large amount of water beyond its normal limits, covering what is usually dry land.
5. eruption: When hot materials like gas, ash, rocks, and lava are released from a volcano. This can be explosive.
10. A strong wind carrying large amounts of sand through the air, especially in desert areas.
11. A cavity in the ground, especially in areas with soluble rock like limestone, formed when the surface layer collapses. They can form suddenly.
13. The rapid movement of a large mass of earth, rock, or debris down a slope.
14. A storm with thunder and lightning, usually with heavy rain and sometimes hail.
15. A sudden shaking of the ground caused by the movement of rocks beneath the Earth's surface. It can sometimes cause great damage.

1. A severe snowstorm characterized by strong winds (often over 35 mph) and very low visibility due to blowing snow.
2. cyclone: A rapidly rotating storm system with strong winds and heavy rain that forms over tropical or subtropical waters. This includes hurricanes and typhoons.
4. A violently rotating column of air that is in contact with both the surface of the Earth and a cloud above it. They are often shaped like a funnel.
6. A large, uncontrolled fire that spreads rapidly, especially in a wilderness or rural area.
7. A large mass of snow, ice, rock, or other material moving quickly down the side of a mountain or slope.
8. A very large sea wave, usually caused by an underwater earthquake or volcanic eruption. They can cause huge destruction when they reach the coast.
9. A storm during which hail (frozen precipitation) falls.
12. A prolonged period of unusually low rainfall, resulting in a severe shortage of water.
