Question

    Which of these green house gas is most abundant in the atmosphere?

    A Carbon dioxide Correct Answer Incorrect Answer
    B Methane Correct Answer Incorrect Answer
    C Nitrous oxide Correct Answer Incorrect Answer
    D Water vapor Correct Answer Incorrect Answer

    Solution

    The most abundant gas is the aqueous phase of the gas in the atmosphere. Water vapor is the most abundant greenhouse gas in the atmosphere. Human activities have only a small direct influence on atmospheric concentrations of water vapor, primarily through irrigation and deforestation, so it is not included in this indicator.
