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. Clouds that form in layers






2. A cloud that produces thunderstorms






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






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






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






6. Forms over land; dry






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






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






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






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






11. Water - in solid or liquid form - that falls from the air to the earth






12. An instrument used to measure relative humidity






13. Develops over the Tropics; warm






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






15. Weather that can cause property damage and even death






16. Small - intense weather systems that produce strong winds - heavy rain - lightning - and thunder






17. An instrument used to measure wind direction






18. An instrument used to measure air pressure






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






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






21. Prefix used to describe high clouds






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






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






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






25. A small - rotating column or air that has high wind speeds and low central pressure and that touches the ground






26. When water vapor condenses near the ground






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






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






29. Prefix used to describe middle clouds






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






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






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






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






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






35. Name the water cycle.






36. An instrument used to measure wind speed






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






38. Lines that connect points of equal air pressure rather than equal elevation






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






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






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






42. An instrument used to measure the amount of rainfall






43. Prefix used to describe lower clouds






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






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






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






47. A large body of air that has similar temperatures






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






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






50. The process by which plants release water vapor into the air through their leaves
