Earths Atmosphere Flashcards
Troposhere
75% of all gases
Water vapor and weather
Atmosphere
Thin layer of gas that covers earth
Protects from suns harmful rays
Keeps us insulated
Ionosphere
Ions that absorb x-ray and gamma
Stratosphere
Contains ozone layer
No water vapor
Greenhouse effect
Gases that allow light into earth but then traps IR
Carbon dioxide. Oxygen. Nox. Methane
Ozone later
03 absorbs UV light
UV
Visible light on EM spectrum
Highly energetic
Radiation
Transfer of energy from sun to earth BY ELECTROMAGNETIC WAVES
IR
Longer wavelengths and just heat
Conduction
Transfer of thermal energy by collision between particles or matter
Convection
Transfer of thermal energy by movement of particles within matter
Molecules are heated and then spread apart. WARM AIR RISES
Air pressure
Amount of pressure exerted from a column of air
Oxygen
21%
Nitrogen
78%
Coriolis effect
Earths rotation causes moving air + water to appear to move to the right or left
Wind
Movement of air from areas of high pressure to low pressure
Global wind belts
Westerlies. West to east
Trade winds. East to west
Polar easterlies. East to west
Jet stream
Narrow band of high winds at the top of the troposphere
Sea breeze
Wind that blows from the sea to land
DAY BECAUSE AIR ABOVE LAND IS WARMER.
Warm land and cold water
Land breeze
Wind that blows from land to sea
NIGHT BECAUSE SEA RETAINS MORE HEAT THAN LAND
Warm water and cold land
