Across
- 4. | A mountain or hill with a vent or crater through which lava, ash, and gases are released from the Earth's interior. Volcanoes can erupt explosively or release lava flows.
- 8. | A celestial object composed of ice, dust, and gas that orbits the Sun. Comets have a glowing tail and can be visible from Earth during certain periods.
- 10. | A sudden shaking or trembling of the Earth's surface caused by the movement of tectonic plates. Earthquakes can vary in intensity and can result in significant damage and destruction.
- 12. | A sudden and powerful electrical discharge that occurs during a thunderstorm. Lightning appears as a bright flash of light in the sky.
- 13. shower | A celestial event in which a large number of meteors or "shooting stars" can be seen radiating from a specific point in the sky. Meteor showers occur when the Earth passes through the debris left by a comet.
- 15. | A violent rotating column of air that is in contact with both the surface of the Earth and a cumulonimbus cloud. Tornadoes are characterized by their funnel shape and destructive winds.
Down
- 1. | A rapid flow of snow down a slope, often triggered by additional snowfall, vibrations, or human activity. Avalanches can be dangerous and cause burial of people and structures.
- 2. | A cascade of water flowing over a steep ledge or rock formation. Waterfalls are often found in rivers and create a stunning sight and soothing sound.
- 3. eclipse | A celestial event in which the Moon passes between the Earth and the Sun, partially or completely blocking the Sun's light. During a solar eclipse, the sky darkens and the Sun appears as a ring or a crescent.
- 5. | A thick cloud of tiny water droplets suspended in the air near the Earth's surface. Fog reduces visibility and creates a misty and mysterious atmosphere.
- 6. | A natural hot spring that periodically ejects a column of water and steam into the air. Geysers are rare and can be found in geothermal areas.
- 7. storm | A strong windstorm that carries large amounts of dust and sand particles. Dust storms can create low visibility and can be hazardous to health and transportation.
- 9. | A beautiful arch of colors that appears in the sky after rain. Rainbows are formed when sunlight is refracted, or bent, and reflected inside raindrops.
- 11. | A natural light display that occurs in the polar regions. Auroras, also known as the Northern Lights (Aurora Borealis) and Southern Lights (Aurora Australis), appear as colorful bands or curtains of light in the sky.
- 14. | A series of large ocean waves triggered by underwater earthquakes, volcanic eruptions, or landslides. Tsunamis can cause widespread devastation when they reach the coastlines.
