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 amount of water vapor or moisture in the air






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






3. 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






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






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






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






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






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






9. When water vapor condenses near the ground






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






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






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






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






14. A cloud that produces thunderstorms






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






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






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






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






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






20. An instrument used to measure air pressure






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






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






23. Forms over water; wet






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






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






26. Clouds that form in layers






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






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






29. Prefix used to describe lower clouds






30. An instrument used to measure wind direction






31. Name the water cycle.






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






33. Develops over the Tropics; warm






34. Forms over land; dry






35. An instrument used to measure the amount of rainfall






36. An instrument used to measure relative humidity






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






38. A large body of air that has similar temperatures






39. Forms over the polar regions; cold






40. Prefix used to describe high clouds






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






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






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






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






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






46. Prefix used to describe middle clouds






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






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






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






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