atmosphere |
nvisible layers of air primarily made of Nitrogen, Oxygen and Argon gases |
|
|
Greenhouse Effect |
Radiation from the sun is reflected by earth and then bounced into the atmosphere where the water particles in the air trap the heat; the water particles remain in the troposphere causing the lowest layer of atmosphere to be warmer |
|
|
troposphere |
Zone where weather occurs; a dense layer of air in which molecules are fueled by sunlight and create energy for weather |
|
|
cumulus clouds- |
Moist air collects rapidly over a small areas |
|
|
stratus |
Air rising gently over a large area and then cools slowly; makes sunlight seemed filtered; they contain ice crystals that can make the sun or moon appear to have a halo |
|
|
cirrus- |
high in the atmosphere and look wispy; they form when water vapor condenses directly into ice crystals |
|
|
air masses |
Large areas of air with the same temperature and moisture levels of the surface |
|
|
cold air mass |
produces cold weather |
|
|
warm air mass |
produces warm weather |
|
|
cold front |
Leading edge of a cold air mass in which the cold air and warm air move towards each other and the warm air rises; these fronts bring snow, thunderstorms, and heavy rains |
