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






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






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






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






5. Prefix used to describe lower clouds






6. A large body of air that has similar temperatures






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






8. An instrument used to measure wind direction






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






10. Name the water cycle.






11. Develops over the Tropics; warm






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






13. Forms over water; wet






14. Prefix used to describe middle clouds






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






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






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






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






19. An instrument used to measure air pressure






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






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






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






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






24. 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






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






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






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






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






29. When water vapor condenses near the ground






30. Clouds that form in layers






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






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






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






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






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






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






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






38. Forms over land; dry






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






40. A cloud that produces thunderstorms






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






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






43. An instrument used to measure the amount of rainfall






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






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






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






47. Forms over the polar regions; cold






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






49. An instrument used to measure relative humidity






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