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. Forms over water; wet






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






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






4. A cloud that produces thunderstorms






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






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






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






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






9. An instrument used to measure wind speed






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






11. 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






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






13. Prefix used to describe high clouds






14. Clouds that form in layers






15. Forms over the polar regions; cold






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






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






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






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






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






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






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






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






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






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






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






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






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






29. An instrument used to measure wind direction






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






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






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






33. Weather that can cause property damage and even death






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






35. Develops over the Tropics; warm






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






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






38. Prefix used to describe middle clouds






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






40. A large body of air that has similar temperatures






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






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






43. An instrument used to measure air pressure






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






45. Name the water cycle.






46. Forms over land; dry






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






48. An instrument used to measure the amount of rainfall






49. Prefix used to describe lower clouds






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