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






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






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






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






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






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






7. Clouds that form in layers






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






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






10. 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






11. An instrument used to measure relative humidity






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






13. Weather that can cause property damage and even death






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






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






16. Develops over the Tropics; warm






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






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






19. A large body of air that has similar temperatures






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






21. An instrument used to measure wind speed






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






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






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






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






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






27. Prefix used to describe lower clouds






28. An instrument used to measure wind direction






29. Prefix used to describe middle clouds






30. Forms over land; dry






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






32. Name the water cycle.






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






34. Forms over the polar regions; cold






35. When water vapor condenses near the ground






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






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






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






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






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






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






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






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






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






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






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






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






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






49. An instrument used to measure air pressure






50. An instrument used to measure the amount of rainfall
