There are three Milankovitch cycles; eccentricity, obliquity, and precession. This video resource explains Earth's tilt, or obliquity, and its precession, which describes Earth's wobble about its axis. These cycles are important for climate change on the order of tens of thousands of years. This resource is recommended for teaching.
