A layer extending an average of 12k above Earth’s surface
Troposphere
Occurs when air temperature increases with altitude & the air becomes stable
Temperature inversion
A natural process in which certain gases in the atmosphere warm a planet as they absorb & emit infrared radiation
Greenhouse effect

What are the 3 basic cloud types?
Stratus, cumulus, & cirrus.
Describe Stratus clouds
Layered, sheet-like associated with rain.
Describe Cumulus clouds
Puffy & occur in fair weather.
Describe Cirrus clouds
Wispy, & high altitude.
Parts of the water cycle
Evaporation Transpiration Condensation Precipitation Infiltration
Is a narrow band of fast-moving, high altitude air.
Jet streams
The apparent deflation of an object due to Earth’s rotation.
Coriolis effect
A large volume of air with uniform moisture & temperature throughout.
Air mass
Where air masses interact in zones.
Weather front
