- 1. measures the humidity in the air
- 4. when droplets of water fall to earth it is called _______
- 5. dark, towering clouds known as thunderclouds
- 6. results in blue skies
- 8. when tiny ice crystals collect and form together, then fall to the earth it is called _________
- 9. when water that has evaporated (water vapor) cools. turns into water droplets, and forms clouds
- 11. thick, low, sheet-like clouds that cover the sky, signal rainy weather; fog is a type of this cloud
- 12. an area where two air masses meet, usually air of different temperatures
- 14. measures wind direction
- 16. thin, curly, wispy clouds made of ice crystals
- 17. rain, sleet, snow, hail, or mixed forms of water that fall to earth from clouds
- 20. the measure of the weight of the atmosphere as it pushes down on earth in a certain area
- 21. water droplets that get caught in updrafts of moving wind and freeze, layer by layer, until the frozen drop grows into a larger ice ball
- 22. daily conditions of wind, temperature, clouds, humidity, and precipitation
- 24. a form of precipitation made of small, semi-transparent balls of ice; occurs when rain/melted snow hits a cool pocket of air before falling to the ground
- 25. the measure of water vapor in the air
- 26. measures air pressure
- 27. results in cloudy weather
Down
- 2. when water heats up, turns into a gas and is drawn into the atmosphere
- 3. large piles of white clouds that can billow high into the sky, look like fluffy cotton
- 7. as precipitation falls, some of it runs off into rivers and streams
- 8. result of air and land masses heating up unevenly because of the earth's position related to the sun and the tilt of the earth
- 10. when water is passed through the leaves of plants and into the atmosphere
- 13. Gauge measures the amount of rainfall in a given area
- 15. the layer of atmosphere where most clouds form and where most weather occurs; 10 km away from earth's surface
- 18. measures air temperature
- 19. the measure of the motion and energy of molecules in the atmosphere, low motion = cold, high motion = warm
- 23. measures wind speed
