Answer: Changes in Earth-Sun relationships, namely Earth's orbit around the sun, axial rotation, and axial tilt
Explanation: Milankovitch cycles refer to changes in the Earth-Sun relations because of the earth's orbital eccentricity that the Earth circles the Sun. The shape of the Earth's path around the sun is eccentricity, due to the constant change of the orbital form within the limits of 0 to 5% ellipticity. In addition, these cycles occur not only due to eccentricity, but also due to axial rotation and axial tilt. All this has an employer of climate change on Earth due to the change in the amount of sunlight. These changes should be understood as very long-term, for example, the Ice Age cycle is associated with changes in the amount of sunlight, and due to changes of Earth's orbit. This means they are important as long-term changes.
