Quizplus · Accepted Answer

Water vapor is the most important naturally occurring greenhouse gas as it is the most abundant and has the greatest impact on Earth's temperature. While carbon dioxide and methane are also important, they are present in much lower concentrations than water vapor. Ozone and nitrous oxide are also greenhouse gases but are not as abundant or significant as water vapor, carbon dioxide, or methane.
