The orbit becomes either more round or more elliptical at these intervals. The shape of the orbit is known as its "eccentricity." A related aspect is the 41,000-year cycle in the tilt of the Earth's axis. Glaciation of the Earth also occurs every 100,000 years.

WebThis changing of the obliquity-- or the changing of the tilt-- is one of these changes in Earth's rotation or Earth's orbit around the sun that might have long-term cycles or effects on Earth's climate, and maybe they do help cause certain ice ages when they act together with each other over certain cycles.
