How does the Milankovitch theory explain intermediate-term climatic events like the Pleistocene
glaciation? According to Milankovitch, variations in what three parameters of Earth's orbit were
responsible for the onset of Pleistocene glaciation? What will be an ideal response?
According to the Milankovitch theory, there is a 100,000-year cycle of eccentricity (departure from a
perfect circle) of Earth's orbit in three areas: the precession of equinoxes, changes in axial tilt, and
orbital eccentricity. This affects the amount of solar radiation coming in at different latitudes,
sometimes resulting in cooling.
