Greenhouse Gases
The gases in our atmosphere that trap heat from the sun are sometimes
called greenhouse gases. Greenhouses are small glass
houses that are used to grow plants. The glass panels of the
greenhouse let in sunlight but keep heat from escaping. This
causes the greenhouse to warm up much like the inside of a
car heats up on a sunny day. The greenhouse gases in our atmosphere
act like the glass panes in a greenhouse. Sunshine gets absorbed
by the earth and the atmosphere. Some of the sun's energy
goes back into space, but much of it remains trapped in our
atmosphere by the greenhouse gases. This is how our planet
stays warm enough for life on earth to survive.
