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






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






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






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






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






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






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






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






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






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






11. Forms over the polar regions; cold






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






13. An instrument used to measure wind speed






14. An instrument used to measure wind direction






15. Forms over water; wet






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






17. An instrument used to measure relative humidity






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






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






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






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






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






23. Prefix used to describe high clouds






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






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






26. An instrument used to measure air pressure






27. Clouds that form in layers






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






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






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






31. Develops over the Tropics; warm






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






33. An instrument used to measure the amount of rainfall






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






35. When water vapor condenses near the ground






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






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






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






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






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






41. 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






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






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






44. Name the water cycle.






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






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






47. Forms over land; dry






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






49. Prefix used to describe lower clouds






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