Key Idea 1
What planet can melt lead with it's surface temperature?
Venus
What is incoming solar radiation composed of?
Ultraviolet, Visible, and Infrared energy
How much of the Sun's light is reflected back into space?
30%
How much energy does Earth absorb into the atmosphere?
70%
Heavier greenhouse gases are caused by what?
Earth not emitting a lot of energy
When the amount of radiation entering the atmosphere is the same as the amount of radiation exiting the atmosphere
Radiation Balance
If the Earth was __ of it’s distance from the Sun then the surface temperature would be __ degrees celsius.
half, 14
What reflects the Suns light?
clouds, ice, snow, sand, vegetation, and bodies of water
___ have longer wavelengths and carry less energy than visible light
Infrared Waves
___ greenhouse gasses = ___ temperatures on earth
heavier, hotter
Distance from the sun, atmosphere's composition, surface temperature, and amount of greenhouse gasses
How do clouds affect Earth's radiation?
They reflect light back into space
What would make the Earth hotter?
True of False: Mars converts the sun's energy into Infrared light
True
Molecules that are greenhouse gasses
Ozone, water, and CFC-11
How hot is the planet Venus?
472`C
vegetation
What causes solar energy reflection for short-term coolness?
Volcanic eruptions
Why Earth is warmer than Mars
Stronger atmosphere that keeps the energy trapped

Radiation intake and outtake have to be ___ to be balanced.
the same
The further from the sun you get, the (less/more) greenhouse gases are emitted.
less
