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






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






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






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






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






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






7. Develops over the Tropics; warm






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






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






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






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






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






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






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






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






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






17. 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






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






19. Clouds that form in layers






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






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






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






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






24. An instrument used to measure wind direction






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






26. An instrument used to measure relative humidity






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






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






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






30. An instrument used to measure wind speed






31. Prefix used to describe middle clouds






32. An instrument used to measure air pressure






33. Prefix used to describe high clouds






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






35. An instrument used to measure the amount of rainfall






36. Name the water cycle.






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






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






39. A cloud that produces thunderstorms






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






41. Prefix used to describe lower clouds






42. A large body of air that has similar temperatures






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






44. Forms over water; wet






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






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






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






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






49. Forms over land; dry






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