What Are Earth's Axis Cycles? | The Milankovitch Cycles Song!

The video tutorial explains Earth's climate change through the Milankovich cycles, which include eccentricity, obliquity, and precession. Eccentricity involves changes in Earth's orbital shape due to gravitational forces, affecting solar radiation. Obliquity refers to the tilt of Earth's axis, influencing seasonal variations. Precession describes the wobble of Earth's axis, impacting seasonal contrasts. These cycles interact to influence Earth's climate over long periods.
