PAP WEATHER UNIT REVIEW Convection Currents 1. If I placed warm air molecules next to cool air molecules would they move? WHY? 2. What effect do convection currents have on weather? (Local and global) 3. Land has a _______ specific heat, so when a hurricane travels over the land it _______ strength. Why? 4. Air flows from _______pressure to ________ pressure. 5. Compare and contrast conduction and convection. 6. __________ air always rises if placed in cold air. 7. Land breeze goes toward _________ and sea breeze goes toward ________. 8. What is THERMAL energy? 9. Changing ____________ and Losing energy are the same thing. 10. ____________________ and ENERGY are the same thing! Hurricanes 1. Land has a _______ specific heat, so when a hurricane travels over the land it _______ strength. Why? 2. The Gulf of Mexico usually produces an increase in Hurricane strength. Explain why this might happen 3. Could a scientist claim that global warming has affected the intensity of hurricanes? Why? 4. Hurricanes begin over east Africa and pick up strength as they travel across the Atlantic. Why should we pay attention to ocean currents in the Atlantic? 5. What effect would a hurricane have on local sea levels? Clouds and “Weather” 1. The prefix Nimbo, or suffix nimbus, refers to a clouds ability to produce _____________. 2. Which cloud is layered? (Circle one) Stratus/cirrus 3. Stratus clouds are __________ and can produce drizzle. NOTE: the prefix nimbo is not always attached to a drizzle producing cloud. 4. When moist warm air smashes into cold dry air it could easily cause a _________ to form. 5. All weather occurs in the ______________ .(atmospheric layer) 6. Describe a Cirrus cloud. 7. Describe a Stratus cloud. 8. Describe a Cumulous cloud. 9. Why do weather forecasters look at the types of clouds in the sky? 10. Where is Tornado alley? Coriolis effect and Global Winds 1. 2. 3. 4. 5. 6. 7. The Coriolis effect is mainly caused by the ____________ of the ___________. Global winds draw air over oceans and onto land. What effect does this have on the weather systems that form over land? ________________, ________________ air comes from a cool ocean. What central area on Earth has the warmest ocean? El Nino occurs off the coast of Peru.(Near the Equator) The air moving onshore from El Nino would be ______________ and ______________. Belts of wind form from rising and falling air. This circular pattern of rising and falling air is known as a _______________ ______________. Where the Convection cells meet there is usually cold dry air. Would this be evidence of High or Low Pressure? Global “Warming” 1. True or False Global Warming appears to be related to the Burning of fossil fuels. 2. The Ocean has ______________ specific Heat. This means it does not change temperature very easily. Why would some claim that the Ocean helps keep the planet temperature under control? 3. The _______________ effect is the name given to a trapping of heat under the layers of the atmosphere. 4. Explain why a hot car on a summer day is a great expample of the Greenhouse effect. 5. The Ozone layer is Located in the st________sphere
