energy Flashcards
what is the name for the wave lengths of radiation that come from earth, what is a common name for it?
infrared.
a common name is heat.
what energy arrives on earth
visible light, and a little bit from the UV( ultra violet) which causes sunburns.
what is incoming solar energy
all of the energy arriving on earth from the sun.
what is incoming solar energy absorbed by:?
atmosphere, clouds, surface. They absorb 69% of solar radiation
what is outgoing solar energy:?
all of the energy being reflected to the earth.
how is outgoing solar energy reflected:?
clouds, surface and aerosols. they select 31% of solar radiation.
outgoing infrared energy:?
the energy that is radiated from the earths surface.
how is energy radiated from the surface:?
infrared radiation, latent heat, sensible heat. the total of all of the ratiations is 69%.
latent heat.:
energy released or absorbed by a body when changing state. tempature of the body remains constant during a change of state, such as melting (o) degrees Celsius or evaporation (100) degrees Celsius.
sensible heat:.
the heat that you can feel. The sensible heat that is possessed by a change in temperature. water in liquid form can increase its temperature between ( o - 100) degrees celcius.
energy absorbed by the universe eventually:.
goes back to the outer space, or atmosphere.
how much solar energy is absorbed by the surface>?.
49%.
how much energy is radiated by the surface>?.
49%.
what percentage of incoming solar radiation leaves the earth again over time.>?.
100%, all of it!.<»/?
