The Greenhouse Effect

 

The greenhouse effect is a natural occurrence that maintains Earth's average temperature at approximately 60 degrees Fahrenheit.

Under normal conditions some of the sun's heat is radiated back into space

The 'Greenhouse Effect' occurs when heat is trapped in the atmosphere by gases
