Conduction
1) Warm front - warm air mass replacing a cold air mass at ground level. Typically shifts wind southeasterly to southwesterly. 2) Cold front - Cold air replacing warm air at ground level. Tyoically shifts southwesterly to northwesterly 3) Stationary front - Equal amount of energy between warm and cold air masses creating a "stalemate".
it is pushed upward
It Cools as it is pushed upward.
They aren't. Clouds are made of water droplets or ice crystals depending on the type.The billowing shape of some clouds is produced by the expansion and upward movement of warm air that is cooled as it rises.
Warm anc cold air colliding are not a direct cause of tornadoes, but they can be a step in the process. where they come from depends on the region the weater system is in. But normally the warm air comes from a warm part of the ocean while the cold air comes from a cold region. In the Central United States, for example, the warm air comes from the Gulf of Mexico while the cold air comes from Canada.
The upward movement of warm air and the downward movement of cold air forms fluids.
Conduction
Convection
Convection
None of the choices are true.
Updraft
Small area storms formed by the strong upward movement of warm, moist air are called storm surges.
Cold Front (:
No. An updraft (updraught) is an upward moving current of warm air.
Cold front.
Warm air is lighter than cold air. So you'll always get warm air on top of cold air when they meet.
