    B. variations in the shape of the Earth's orbit

    Explanation:

    Ice age cycles according to Milutin Milanković who was a Serbian geophysicist and climatologist can be defined as the glacial and interglacial cycles or periods which occurs due to the unsteady movement of the Earth in its orbit. This unsteady movement resulted in a change in way solar energy was been distributed on the surface of the Earth.

    The ice age cycles are referred

    to as Milutin Milanković cycles. The ice age cycles according to Milutin Milanković has two cycles, the shorter cycle is for an average of 100,000 years while the longer cycle is for an average of 413,000 years.

    These ice age cycles are important because they have an effect on the Earth's climate. Such effects include

    a. The way ice is been formed on the earth.

    b. The distribution of solar energy from the sun or the amount of sunlight exposure to the regions on the earth.

    One of the factors contributing to the ice age cycles is the variations in the

    shape of the Earth's orbit.
