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






2. 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






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






4. Forms over the polar regions; cold






5. Prefix used to describe lower clouds






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






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






8. Prefix used to describe middle clouds






9. Name the water cycle.






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






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






12. Forms over water; wet






13. A large body of air that has similar temperatures






14. When water vapor condenses near the ground






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






16. Develops over the Tropics; warm






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






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






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






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






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






22. Forms over land; dry






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






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






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






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






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






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






29. An instrument used to measure relative humidity






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






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






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






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






34. Weather that can cause property damage and even death






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






36. Clouds that form in layers






37. An instrument used to measure the amount of rainfall






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






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






40. An instrument used to measure wind speed






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






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






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






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






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






46. Dark stratus clouds that usually produce light to heavy - continuous rain






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






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






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






50. A cloud that produces thunderstorms
