- (I)Just as the glass in a greenhouse holds the
sun's warmth inside, so the atmosphere traps
the sun's heat near the Earth's surface and
keeps the Earth warm. (II) Tiny quantities of
greenhouse gases in the atmosphere trap the
sun's heat, warming land, air and water. (III) We
call this the natural greenhouse effect. (IV) If it
were not for the natural greenhouse effect, the
Earth would be like the moon, too cold to
support life. (V) The glass panels of the
greenhouse let in light but keep heat from
escaping.
