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






2. A large body of air that has similar temperatures






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






4. An instrument used to measure air pressure






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






6. Prefix used to describe middle clouds






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






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






9. Clouds that form in layers






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






11. An instrument used to measure wind speed






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






13. A cloud that produces thunderstorms






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






15. An instrument used to measure the amount of rainfall






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






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






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






19. Prefix used to describe lower clouds






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






21. When water vapor condenses near the ground






22. Forms over water; wet






23. Forms over the polar regions; cold






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






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






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






27. Develops over the Tropics; warm






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






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






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






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






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






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






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






35. An instrument used to measure relative humidity






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






37. Weather that can cause property damage and even death






38. Prefix used to describe high clouds






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






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






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






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






43. 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






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






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






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






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






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






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






50. An instrument used to measure wind direction
