Atmospheric gases allow sunshine to pass through but absorb heat that is radiated back from the surface of the earth. This acts as a blanket keeping heat.

Presentation transcript:

Atmospheric gases allow sunshine to pass through but absorb heat that is radiated back from the surface of the earth. This acts as a blanket keeping heat close to the earth’s surface.

Greenhouse Effect Incoming solar radiation = short wavelength Outgoing infrared radiation = long wavelength

Solar Radiation Infrared Radiation

-essential, natural process that helps keep earth warm -too much greenhouse gas increases effect and leads to global warming
