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






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






3. An instrument used to measure air pressure






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






5. A large body of air that has similar temperatures






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






7. Forms over land; dry






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






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






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






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






12. 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






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






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






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






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






17. Forms over water; wet






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






19. Prefix used to describe middle clouds






20. When water vapor condenses near the ground






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






22. Name the water cycle.






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






24. Prefix used to describe high clouds






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






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






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






28. An instrument used to measure the amount of rainfall






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






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






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






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






33. Prefix used to describe lower clouds






34. Clouds that form in layers






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






36. An instrument used to measure wind speed






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






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






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






40. An instrument used to measure wind direction






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






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






43. An instrument used to measure relative humidity






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






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






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






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






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






49. Develops over the Tropics; warm






50. Forms over the polar regions; cold
