Ch.9.2 energy transfer in the atmosphere
Radiation traveling though space
Convection in air
Conduction of air
Heating from below
Air poor heat conducter
Conduction only warms layer of earth
Conduction:process that heats air close to earth surface
Expanding air
Rising and sinking air
Air circulation patterns
When air is stable
Mean moving faster and becoming father apart
When air expands density doesn’t
Tempurture of air increase kinectic energy of molecules increase
When air is hot it rises while cold is also helping to move up
When temperature is equal to outside it stops
Air is close it warm up like hot air balloon
When cold air moves closer to heater warm up
The thing with a heater and cold air is convection
Warm air near a heater on floor rises as density decrease
It is good for air to go as far as way as possible if it was pollutant
An inversion is where air is to dense
When warm air sits on cold air it means air rising
Absorbing different wavelengths
Greenhouse gases
Heating with sunlight
Energy in the troposphere
Maintaining radiation balance
Energy from the sun is distributed though the troposphere
Radiation from the sum heats earths surface unevenly put more energy consentrated and equaltorial region then polar
Concentrated sunlight can be used as source of heat
As a magnify can heat by consentrate on one spot
While the shaded is vibrating it and making it hotter
Ultra violet is harmful to animals and plants
The ozone layer is the layer that absorbs the most ultra violet
Only 7 percent of suns radiation consisting of ultra violet radiation
The amount of solar radiation reaching earth surface is equal to the amount of outgoing radiation form earth surface
Solar radiation that reaches earth surface is absorbed by land,trees,asphalt,sand ,soil and ocean
Gases that that strongly absorbs some of earths outgoing radiation is greenhouse gases
Some of years have presenting that every year earth temp is getting hotter this is global warming
Earth outgoing radiation is greenhouse gases
Etmitting radiation
Radiation etmitted from the sun is mostly in visible range and earth is infrared
Your own body edmitts infrared radiation known as heat
