  1. PAP WEATHER UNIT REVIEW

  2. Convection Currents • If I placed warm air molecules next to cool air molecules would they move? WHY? • What effect do convection currents have on weather? (Local and global) • Land has a _______ specific heat, so when a hurricane travels over the land it _______ strength. Why? • Air flows from _______pressure to ________ pressure. • Compare and contrast conduction and convection. • __________ air always rises if placed in cold air. • Land breeze goes toward _________ and sea breeze goes toward ________. • What is THERMAL energy? • Changing ____________ and Losing energy are the same thing. • ____________________ and ENERGY are the same thing!

  3. Hurricanes • Land has a _______ specific heat, so when a hurricane travels over the land it _______ strength. Why? • The Gulf of Mexico usually produces an increase in Hurricane strength. Explain why this might happen • Could a scientist claim that global warming has affected the intensity of hurricanes? Why? • 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?

  4. Clouds and “Weather” • The prefix Nimbo, or suffix nimbus, refers to a clouds ability to produce _____________. • Which cloud is layered? (Circle one) Stratus/cirrus • Stratus clouds are __________ and can produce drizzle. NOTE: the prefix nimbo is not always attached to a drizzle producing cloud. • When moist warm air smashes into cold dry air it could easily cause a _________ to form. • All weather occurs in the ______________ .(atmospheric layer) • Describe a Cirrus cloud. • Describe a Stratus cloud. • Describe a Cumulous cloud. • Why do weather forecasters look at the types of clouds in the sky? • Where is Tornado alley?

  5. Coriolis effect and Global Winds • 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?

  6. Global “Warming” • True or False Global Warming appears to be related to the Burning of fossil fuels. • 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? • The _______________ effect is the name given to a trapping of heat under the layers of the atmosphere. • Explain why a hot car on a summer day is a great expample of the Greenhouse effect. • The Ozone layer is Located in the st________sphere
