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






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






3. Forms over the polar regions; cold






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






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






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






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






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






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






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






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






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






13. When water vapor condenses near the ground






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






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






16. Prefix used to describe lower clouds






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






18. A cloud that produces thunderstorms






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






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






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






22. Name the water cycle.






23. Prefix used to describe middle clouds






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






25. An instrument used to measure the amount of rainfall






26. An instrument used to measure wind speed






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






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






29. An instrument used to measure relative humidity






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






31. Develops over the Tropics; warm






32. Forms over land; dry






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






34. Forms over water; wet






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






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






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






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






39. An instrument used to measure air pressure






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






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






42. 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






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






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






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






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






47. Weather that can cause property damage and even death






48. A large body of air that has similar temperatures






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






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