Heat from the sun shines onto the Earth.
It passes through a blanket of gases in our
atmosphere.
3
Some of the heat energy is reflected back into
space.
Some of the heat energy gets absorbed by the
blanket of gases.
4
The greenhouse gases are essential to life on
Earth. Without them heat energy would escape back
into space.
Earth would be a very chilly place with an
average temperature of -18C !
5
The greenhouse gases help to keep the temperature
of the earth in balance. This process is called
the GREENHOUSE EFFECT.
The gases work a bit like glass in a greenhouse
to trap in warmth. But the earth is getting
warmer and warmer. WHY?
6
Human activities are creating more greenhouse
gases including carbon dioxide, CO2.
7
More greenhouse gases in the atmosphere mean that
more heat energy is absorbed.
We call this increase in the temperature of the
earthglobal warming.
