Greenhouse effect:

____________ radiation from the _________ hits the Earth where it is transformed into ____________ energy.  The earth warms and gives off  _______________ radiation which is absorbed by greenhouse gases like _________, __________, ___________, _____________.  The greenhouse gases convert the energy into _______________ energy.  Eventually the greenhouse gases give off the energy in the form of ____________  which either leaves the atmosphere or ______________________________________________.  Because the radiation given off by the Earth is not all radiated back to space, the Earth is _________________.
