Natural Phenomenon

3. A series of large ocean waves triggered by an underwater disturbance, such as an earthquake or volcanic eruption
6. Natural light display in the sky, predominantly seen in polar regions, caused by the interaction of solar particles with the Earth's magnetic field
8. An extended period of abnormally low rainfall resulting in a shortage of water
9. A rapid flow of snow down a slope, often triggered by a disturbance such as an earthquake or skier's movement
10. A severe snowstorm characterized by strong winds, low visibility, and cold temperatures
11. The obscuring of one celestial body by another, such as a solar eclipse (the Moon blocking the Sun) or a lunar eclipse (the Earth blocking the Moon)
13. A storm characterized by falling balls or lumps of ice called hail
14. A violent rotating column of air extending from a thunderstorm cloud to the ground
15. A thick cloud of tiny water droplets suspended in the air near the ground, reducing visibility

1. Sudden shaking or trembling of the ground caused by the movement of tectonic plates beneath the Earth's surface
2. A cascade of water flowing over a steep cliff or rock formation
4. A celestial object consisting of a nucleus of ice and dust that orbits the Sun and develops a bright, glowing tail when near the Sun
5. A colorful arc in the sky caused by the reflection, refraction, and dispersion of light in water droplets
7. A storm characterized by thunder, lightning, heavy rain, and sometimes strong winds
12. A mountain or hill with a vent or crater through which molten rock, ash, and gases are ejected
