== Orbital changes == Astronomical cycles (also known as Milankovitch cycles) are variations of the Earth's orbit around the Sun due to the gravitational interaction with other masses within the Solar System. Due to this cyclicity, solar irradiation differs through time on different hemispheres and seasonality is affected. These insolation variations have influence on Earth's climate and on the deposition of sedimentary rocks.
