2.5 Air Masses and Winds Practice

Master air masses & winds! Practice identifying types, heat transfer, and pressure systems.

Wind Wind always blows from high pressure to low pressure. What is the name of a wind that blows south-->north? north south northeast southwest Air Masses Match the features of the air masses to their names. continental dry forms over land c polar cold forms between 60° and 90° N P tropical T warm forms between 0° and 25° N maritime m humid forms over the ocean Heat Transfer Matching radiation light conduction direct contact convection hot water or air moving What is the name of a wind that blows northeast-->southwest? north south northeast southwest Label the Air Masses Label the air masses with the correct abbreviations. You will use some abbreviations more than once. Spelling and capitalization matter!mPmTcPcT mP cP cP mP mT cT mT mT What is the name of a wind that blows east-->west? east south west southwest What organisms first added oxygen to the atmosphere? cyanobacteria trees animals volcanoes What type of heat transfer warms the troposphere? conduction radiation convection Composition of Earth's Atmosphere Today 78% nitrogen 21% oxygen 1% other (everything else together) Warm air is _ than cold air, so it will _. more dense; rise less dense; rise more dense; sink less dense; sink In the Northern Hemisphere, the Coriolis Effect pushes objects and wind to the _ because of _. left, Earth's gravity right, Earth's gravity left, Earth's rotation right, Earth's rotation Identifying Air Masses Fill out the table below using the map.
