Question

Quizplus · Accepted Answer

The principal greenhouse gases in our present atmosphere are water vapor and carbon dioxide. These gases trap heat and contribute to the warming of the planet, known as the greenhouse effect. While other gases such as methane and nitrous oxide also contribute to the greenhouse effect, water vapor and carbon dioxide are the most abundant and have the greatest impact on climate change. Water vapor and carbon dioxide are the two most abundant greenhouse gases in our present atmosphere. While other gases such as methane and nitrous oxide also contribute to the greenhouse effect, their concentrations are much lower than that of water vapor and carbon dioxide.
