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. Thin - feathery - white clouds found at high altitudes






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






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






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






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






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






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






9. Forms over the polar regions; cold






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






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






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






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






14. Prefix used to describe high clouds






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






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






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






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






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






20. An instrument used to measure relative humidity






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






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






23. Forms over water; wet






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






25. A large body of air that has similar temperatures






26. Name the water cycle.






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






28. An instrument used to measure air pressure






29. Weather that can cause property damage and even death






30. A cloud that produces thunderstorms






31. An instrument used to measure wind direction






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






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






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






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






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






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






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






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






41. Forms over land; dry






42. When water vapor condenses near the ground






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






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






45. Clouds that form in layers






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






47. Develops over the Tropics; warm






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






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






50. An instrument used to measure the amount of rainfall
