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. Weather that can cause property damage and even death






2. Prefix used to describe high clouds






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






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






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






6. A large body of air that has similar temperatures






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






8. An instrument used to measure relative humidity






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






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






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






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






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






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






15. Puffy - white clouds that tend to have flat bottoms






16. Most common form of solid precipitation; falls in individual ice crystals or combines to form snowflakes






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






18. Forms over the polar regions; cold






19. Name the water cycle.






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






21. An instrument used to measure wind speed






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






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






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






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






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






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






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






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






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






31. Forms over land; dry






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






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






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






35. When water vapor condenses near the ground






36. An instrument used to measure air pressure






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






38. A cloud that produces thunderstorms






39. An instrument used to measure wind direction






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






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






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






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






44. Clouds that form in layers






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






46. Forms over water; wet






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






48. Prefix used to describe middle clouds






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






50. Prefix used to describe lower clouds
