    Consider the following statements regarding obliqueness of the earth;
    1. The earth's axis varies from \[22.1{}^\circ \] to \[24.5{}^\circ \] during a cycle of about 41,000 years.
    2. The present inclination is 23.5 to the vertical.
    3. It causes the tropics and polar cycle to be displaced.
    4. It influences temperature differences.

    A)  1, 2 are correct

    B)  2, 3 are correct

    C)  3, 4 are correct

    D)  All the above are correct

    Correct Answer: D

    Solution :

    [d] The variation is angle of inclination of earth's axis from 22.1 to \[24.5{}^\circ \]is called obliquity and influences temperature differences between summer and winter. The obliquity is among the three periodic deviations in relative positions of Earth and Sun, the other two being Eccentricity and Precession.
