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 cold air mass meets and pushes up the less-dense cold air






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






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






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






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






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






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






8. A cloud that produces thunderstorms






9. Forms over water; wet






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






11. An instrument used to measure air pressure






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






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






14. Clouds that form in layers






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






16. 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






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






18. An instrument used to measure wind direction






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






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






21. Prefix used to describe middle clouds






22. When water vapor condenses near the ground






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






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






25. Weather that can cause property damage and even death






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






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






28. Forms over land; dry






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






30. Name the water cycle.






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






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






33. An instrument used to measure the amount of rainfall






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






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






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






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






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






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






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






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






42. Prefix used to describe high clouds






43. An instrument used to measure relative humidity






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






45. Prefix used to describe lower clouds






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






47. A large body of air that has similar temperatures






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






49. Develops over the Tropics; warm






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