Oxygen (O2) and nitrogen (N2) do not have much greenhouse effect, but several trace gases including carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and various chlorofluorocarbons are important greenhouse gases. The primary mechanism by which these greenhouse gases warm the Earth is:A. Preventing convection currents that take heat aloft, in the same way that the glass of a greenhouse stops convection currents and so makes the air in the greenhouse warmer. B. Raising the atmospheric pressure, because squeezing air warms it, as we saw at the Redwoods. C. Experiencing chemical reactions with each other, which release energy. D. Absorbing some of the infrared radiation emitted from the Earth. E. Making politicians mad, so they give speeches that heat the air.

Answer:A. Preventing convection currents that take heat aloft, in the same way that the glass of a greenhouse stops convection currents and so makes the air in the greenhouse warmer.

Explanation: when ultraviolet solar radiation penetrates into the Earth's atomosphere and heats it,

the conventional radiation is supposed to be radiated back into the atmosphere as heat. however this is prevented from happening due to green house gases, they absorb the radiant heat and retain this heat within the Earth's environment and so behaves like the glass barrier in green houses. these green house gases trap heat within the Earth causing global warming.
