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. The boundary between to different air masses when they meet






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






3. An instrument used to measure wind speed






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






5. Prefix used to describe high clouds






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






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






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






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






10. Forms over the polar regions; cold






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






12. A large body of air that has similar temperatures






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






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






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






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






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






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






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






20. An instrument used to measure the amount of rainfall






21. An instrument used to measure wind direction






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






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






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






25. Weather that can cause property damage and even death






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






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






28. Develops over the Tropics; warm






29. When water vapor condenses near the ground






30. Name the water cycle.






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






32. An instrument used to measure air pressure






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






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






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






36. Prefix used to describe middle clouds






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






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






39. 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






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






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






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






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






44. Forms over land; dry






45. A cloud that produces thunderstorms






46. An instrument used to measure relative humidity






47. Prefix used to describe lower clouds






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






49. Forms over water; wet






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