Name ___________________________________ Date ____________________ Period _________ Weather Test Review Multiple Choices 8. Look carefully at the graphic below. What sort of weather would you expect to find within the circle? Dry and Hot summers with cold and moist winters 1. Cloudy and rainy weather is usually associated with what type of pressure system? _____. a. Warm front (rain/clouds for a few days) b. Cold front (rain/clouds initially then clear) c. Stationary front (rain/clouds for many days) 2. What type of pressure occurs when air masses sinks and prevents clouds from forming_____. a. High pressure b. Low pressure 9. A tornado is a type of severe weather that is NOT an intense tropical storm? a. True b. False c. Only when it is close to an ocean 3. Tornadoes and hurricanes are produced by a. Thunderstorms b. Volcanoes c. Tsunamis 10. Where is the calmest part of a hurricane? a. Vortex b. Eye c. outside 4. What is wind? How does it form? Air moving from high pressure to low pressure Uneven heating of Earth’s surface 5. A front is formed between a cold and _____ air masses. a. Cold b. Warm 11. True or False? a. Hurricanes are much larger than tornadoes true b. Tornadoes last for a longer time than Hurricanes false c. Hurricanes are associated with flooding since they cause high waves and strong rains true 6. Which type of system is shown below? High 7. Which type of system is shown below? Low 12. How does air move in a low-pressure system? a. Toward the low-pressure area b. Away from the low-pressure area c. Clockwise around the low-pressure area 13. A thermometer measures ______________? a. Air mass b. Air temperature c. Dew point 14. How do ocean currents affect weather? The temperature of the water will influence/make the air the same temperature 15. A maritime tropical air mass would have the greatest effect on weather _________. a. Seattle b. Florida c. Alaska 16. Explain how a hurricane forms? The ocean provides warm and moist air to fuel the hurricane 17. The amount of water vapor in the air relative to what that air could hold is the _____. a. Dew point b. Air pressure c. Relative humidity 18. Air moves into and upward through a _______ system. a. High pressure b. Low c. Warm front 19. A continental polar air mass would have the greatest effect on weather in ___________. a. Florida b. Alaska c. Texas 25. Which weather phenomenon do the trade winds weaken or change direction? a. El Nino b. La Nina c. Tornado d. Hurricane 26. Where do warm ocean currents originate? Equator 27. What causes the winds to move in a circular directions instead of a straight line? Coriolis Effect 28. Explain why air masses tend to travel from the Polar Regions to the equator? Hot air rises at the equator. Cool dense air moves in to fill in the space. 20. Clear skies and fair weather is brought in by which type of system? a. High b. Low c. Warm front 21. _________________ is the atmospheric conditions, along with short-term changes, of a certain place at a certain time a. Climate b. Weather c. season 22. A (n) ________________ forms when warmer air moves toward colder, denser air. a. Cold front b. Warm front c. Stationary front 23. Cooler air has _______________ humidity than warmer air. a. More b. Less c. Same d. 24. When a build-up of warm water occurs off the coast of South America, what weather phenomenon is this? a. La Nina b. El Nino 29. Using the diagram above, explain how the Gulf Stream helps regulate the temperature in Western Europe. The warm water flows north and across the Atlantic to Western Europe. This warm water warms the air above it making the weather warmer than it would be if the current did not move past that area. C . B . A D A. B. C. D. Using the weather map above name and describe what is occurring at each letter Cold Front: Cooler air, rainy/cloudy then clear High Pressure System: Clear Skies/ Fair weather Low Pressure System: Cloudy/Rainy weather Warm Front: Warmer air, cloudy/rainy for a few days.
