Weather And Climate

Subject : science
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Puffy - white clouds that tend to have flat bottoms






2. The temperature to which air must cool to be completely saturated






3. A cold air mass meets and pushes up the less-dense cold air






4. The amount of moisture that air contains compared with the maximum amount it can hold at a particular temperature






5. Occurs when water vapor cools and changes back to liquid droplets; how clouds form






6. Occurs when liquid water changes into water vapor - which is a gas






7. Water vapor condensing on grass - forming small water droplets






8. Solid precipitation that falls as balls or lumps of ice






9. Occurs when rain - snow - sleet - or hair falls from the clouds onto the earth's surface






10. An instrument used to measure relative humidity






11. A large body of air that has similar temperatures






12. A warm air mass meets and moves a cold air mass - eventually replacing it






13. Forms over the polar regions; cold






14. A wall of water that builds up over the ocean due to the heavy winds and low atmospheric pressure






15. Used to find the location - movement - and intensity of precipitation






16. Water - usually from precipitation - that flows across land and collects in rivers - streams - and eventually the ocean






17. A prediction of weather conditions over the next three to five days






18. Prefix used to describe lower clouds






19. Forms over water; wet






20. An instrument used to measure air pressure






21. A collection of millions of tiny water droplets or ice crystals






22. When rain does not freeze until it hits a surface near the ground






23. A large electrical discharge that occurs between two oppositely charged surfaces






24. The condition of the atmosphere at a particular time and place






25. A cloud that produces thunderstorms






26. When water vapor condenses near the ground






27. Develops over the Tropics; warm






28. Prefix used to describe middle clouds






29. An instrument used to measure wind direction






30. Orbit the earth and provide the images of the swirling clouds you can see of television weather reports






31. Freezing rain; forms when rain falls through a layer of freezing ice






32. An instrument used to measure the amount of rainfall






33. The most common form of precipitation; liquid water that falls in droplets






34. The amount of water vapor or moisture in the air






35. An instrument used to measure wind speed






36. Continuous movement of water sources - such as lakes and oceans - into the air - onto and over land - into the ground - and back to water sources






37. A large - rotating tropical weather system with wind speeds of at least 119 km/h; sometimes called typhoons or cyclones






38. The sound the results from the rapid expansion of air along the lightning strike






39. When it is a part of a cloud's name - it means that precipitation might fall from the cloud






40. Thin - feathery - white clouds found at high altitudes






41. A tool used to measure air temperature that is usually filled with alcohol or water that is coloured red or mercury






42. Prefix used to describe high clouds






43. A faster-moving cold air mass overtakes a slower-moving air mass and forces the warm air up






44. When air holds all the water it can at a given temperature






45. The boundary between to different air masses when they meet






46. A small circle - which shows the location of the weather station - with a set of symbols and numbers surrounding it - which represent weather data






47. The process by which a gas - such as water vapor - becomes a liquid - such as water






48. Name the water cycle.






49. A cold air mass meets a warm air mass and little horizontal movement occurs






50. Forms over land; dry
