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 air holds all the water it can at a given temperature






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






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






4. Prefix used to describe lower clouds






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






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






7. Develops over the Tropics; warm






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






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






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






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






12. Forms over water; wet






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






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






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






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






17. Name the water cycle.






18. Prefix used to describe middle clouds






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






20. An instrument used to measure wind direction






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






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






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






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






25. 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






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






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






28. Prefix used to describe high clouds






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






30. An instrument used to measure relative humidity






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






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






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






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






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






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






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






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






39. A cloud that produces thunderstorms






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






41. A large body of air that has similar temperatures






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






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






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






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






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






47. An instrument used to measure the amount of rainfall






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






49. Clouds that form in layers






50. An instrument used to measure air pressure
