Milankovitch cycles describe the effects of changes as a result of climate change. There are three Milankovitch cycles:about Earth's Eccentricity (the shape
of the Earth's orbit around the Sun), Axial tilt (the inclination of the Earth's axis in relation to its plane of orbit around
the Sun) and precession (the Earth's slow wobble as it spins on axis).
According to this, Milankovitch's cycles <span>are changes in earth's rotation and orbit around the sun that may trigger climate variation. (B).</span>
