Explain the atmospheric chemistry of earth's greenhouse gases and their effect on the greenhouse effect, if any.

• Greenhouse gases are composed of carbon dioxide, methane, and water vapor. They allow the sun's rays to penetrate the atmosphere, reach the surface and are reflected back toward the atmosphere, then the greenhouse gases reflect them back to the surface. This traps heat between the surface of Earth and the atmosphere preventing the earth from cooling too much for life to exist.

• Greenhouse gases are composed of methane, carbonic nitrates, and water vapor. They prevent the sun's rays from penetrating the atmosphere to reach the surface instead they are reflected back to the surface. This releases heat between the surface of Earth and the atmosphere.

• Greenhouse gases are composed of carbon dioxide, methane, and nitrogen. They allow the sun's rays to get through to reach the surface and are reflected back and forth between atmosphere then back to the surface. This keeps heat between the surface of Earth and the atmosphere preventing the earth from cooling too much for life to exist.

• Greenhouse gases are composed of nitrogen, oxygen, carbon dioxide, methane, and water vapor but they have no effect on earth's greenhouse effect.
