Across
- 5. The process by which molecules at the surface of a liquid absorb enough energy to change to a gas
- 6. A rapidly whirling, funnel-shaped cloud that reaches down to touch Earth’s surface
- 7. The continual movement of water among Earth’s atmosphere, oceans, and land surface through evaporation, condensation, and precipitation
- 8. The temperature at which condensation begins
- 12. The amount of water vapor in a given volume of air
- 13. Band of high-speed winds about 10 kilometers above Earth’s surface
- 17. A swirling center of low air pressure
- 18. A tropical storm that has winds of about 119 kilometers per hour or higher
- 20. A long period of low precipitation
- 22. The boundary where unlike air masses meet but do not mix
- 23. Any form of water that falls from clouds and reaches Earth’s surface as rain, snow, sleet, or hail
Down
- 1. The horizontal movement of air from an area of high pressure to an area of lower pressure
- 2. The percentage of water vapor in the air compared to the maximum amount of water vapor that air can contain at a particular temperature
- 3. A huge body of air that has similar temperature, humidity, and air pressure at any given height
- 4. An overflowing of water in a normally dry area
- 9. A high-pressure center of dry air
- 10. The change of state from a gas to a liquid
- 11. pressure The pressure caused by the weight of a column of air pushing down on an area
- 14. A violent disturbance in the atmosphere
- 15. Elevation above sea level
- 16. A small storm, often accompanied by heavy precipitation and frequent thunder and lightning
- 19. The relatively thin layer of gases that forms Earth’s outermost layer
- 21. A “dome” of water that sweeps across the coast where a hurricane lands
