Greenhouse Gases Are Essential To Support Life On Earth at Life

Greenhouse Gases Are Essential To Support Life On Earth. The major greenhouse gas, carbon dioxide, emitted naturally and by the burning of fossil fuels, stays in the atmosphere a long time. Greenhouse gases allow the sun’s light to shine onto earth’s surface, and then the gases, such as ozone, trap the heat that reflects back from the surface inside earth’s atmosphere.

When energy from the sun first reaches us, it does so mainly as light. Of other greenhouse gases, earth would be. The greenhouse effect happens when certain gases—known as greenhouse gases—collect in earth’s atmosphere.

Greenhouse gases are gases—like carbon dioxide (co 2 ), methane, and nitrous oxide—that keep the earth warmer than it would be without them. The diameter of earth is 12,742km and the atmosphere is about 100km thick. When energy from the sun first reaches us, it does so mainly as light. Greenhouse gases allow the sun’s light to shine onto earth’s surface, and then the gases, such as ozone, trap the heat that reflects back from the surface inside earth’s atmosphere.
