The greenhouse effect is the processby which heat from the Sun builds

up near Earth’s surface and istrapped by the atmosphere.

13

Look at the 4 steps on the next slide.Number the steps in order

from 1 through 4 as they explainthe order of the greenhouse effect.

13

Heat rays from Earth riseinto the atmosphere.

Water vapor, carbon dioxide, andother gases trap some heat rays,and the atmosphere warms up.

Sun’s rays strike the Earth.

Some heat rays escapeinto space.
