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






2. Forms over land; dry






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






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






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






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






7. A large body of air that has similar temperatures






8. An instrument used to measure relative humidity






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






10. Develops over the Tropics; warm






11. Forms over the polar regions; cold






12. Forms over water; wet






13. Prefix used to describe lower clouds






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






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






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






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






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






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






20. 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






21. An instrument used to measure the amount of rainfall






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






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






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






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






26. An instrument used to measure wind speed






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






28. An instrument used to measure wind direction






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






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






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






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






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






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






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






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






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






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






39. Name the water cycle.






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






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






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






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






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






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






46. Prefix used to describe high clouds






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






48. When water vapor condenses near the ground






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






50. Prefix used to describe middle clouds
