Across
- 2. long periods of unusually low precipitation_
- 6. the amount of mass in a given volume
- 8. the horizontal movement of air from an area of high pressure to an area of low pressure
- 11. (two words)winds that blow steadily from specific directions over long distances, the movement of air between the equator and the poles produces global winds.
- 12. (two words)bands of high-speed winds about 10 kilometers above Earth's surface
- 16. lines joining places that have the same temperature
- 17. (two words)there is a possibility for the storm
- 19. any form of water that falls from clouds and reaches Earth's surface, common types of precipitation include, rain, sleet, freezing rain, hail, and snow.
- 20. a measure of the amount of water vapor in the air
- 22. elevation above sea level
- 23. chlorine compounds formerly used in air conditioners, refrigerators, and spray cans; also called CFCs
- 25. a violent disturbance in the atmosphere
- 26. (two words)the temperature at which condensation begins
- 28. the area where the air masses meet and do not mix
- 29. the condition of the Earth's atmosphere at a particular time and place
- 31. the average, year-after-year conditions of temperature, precipitation, winds, and clouds in an area
- 32. lines joining places on the map that have the same air pressure
- 33. (three words) the is the continuous process by which water moves through the living and nonliving parts of the environment
- 34. the force pushing on an area or surface
- 35. scientists who study the causes of weather and try to predict it
- 37. (two words)a storm has been spotted, prepare yourself
Down
- 1. (two words)an event that occurs every two to seven years in the Pacific Ocean, during which winds shift and push warm surface water toward the coast of South America; it can cause dramatic climate changes.
- 3. (two words)the percentage of water vapor in the air compared to the maximum amount the air could hold
- 4. the distance from the equator, measured in degrees
- 5. wispy, feathery clouds made mostly of ice crystals that form at high levels, above about 6 kilometers
- 7. clouds that form less than 2 kilometers above the ground and look like fluffy, rounded piles of cotton
- 9. an instrument that is used to measure changes in air pressure.
- 10. (three words) the increased cooling that a wind can cause
- 11. (two words) the process by which gases hold heat in the air
- 13. a tool that measures the relative humidity.
- 14. (two words) winds that blow over short distances, local winds are caused by unequal heating of Earth’s surface within a small area.
- 15. (two words)a gradual increase in the temperature of Earth's atmosphere
- 18. the climate characteristic of a small specific area; it may be different from the climate of the surrounding area
- 21. A tool used to measure wind speed
- 24. Effect (two words)named for a French mathematician) – the way Earth’s rotation makes winds in the Northern Hemisphere curve to the right and winds in the Southern Hemisphere curve to the left
- 27. (two words) gases in the atmosphere that trap heat
- 30. the layer of gasses that surrounds the planet
- 36. clouds that form in flat layers
