    If there was no \[C{{O}_{2}}\] in the earth's atmosphere, the temperature of earth's surface would be

    A) higher than the present

    B) dependent on the amount of oxygen in the atmosphere

    C) same as present

    D) less than the present.

    Correct Answer: D

    Solution :

    Carbon dioxide is one of the important green-house gas. It allows the shorter wavelength of infra-red radiations to pass through it but does not allow these radiations to leave the earth's atmosphere. This results in warming of the atmosphere. If the amount of \[C{{O}_{2}}\] decreases then there will not be any increase in temperature.
