Detailed explanation-1: -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. The gases act like the glass walls of a greenhouse-thus the name, greenhouse gas.
Detailed explanation-2: -How Does the Greenhouse Effect Work? Solar energy absorbed at Earth’s surface is radiated back into the atmosphere as heat. As the heat makes its way through the atmosphere and back out to space, greenhouse gases absorb much of it.
Detailed explanation-3: -The gases act like the glass walls of a greenhouse – hence the name, greenhouse gases. Without this greenhouse effect, temperatures would drop to as low as-18˚C (-0.4˚F); too cold to sustain life on earth.
Detailed explanation-4: -Greenhouse gases in the atmosphere (methane, carbon dioxide, etc.) let visible light pass through, but absorb infrared light – causing the atmosphere to heat up.
