In Stage 8, you learnt how carbon dioxide concentration in the atmosphere has been steadily increasing. Carbon dioxide is a greenhouse gas, which traps heat energy in the atmosphere and keeps the Earth warm.
Look at this diagram. It is similar, but not identical, to one that you may remember.
With a partner, match each of these statements to one of the numbers on the diagram.
A Some of the reflected energy passes back out through the atmosphere and is lost to space.
B Energy from the Sun passes through the atmosphere and warms the surface of the ground.
C Some of the reflected energy is blocked by carbon dioxide in the atmosphere, so it stays close to the Earth.
D Some of the energy that reaches the ground is reflected.
