Reincarnation of The Four Seasons

In astronomy, the season division is determined by the position of the Earth around the orbit of the Sun. When the earth is at different times in the year, when it is in different positions of the orbit, the sun is different in all parts of the earth, and the heat received by the sun is different, resulting in seasonal changes and differences between hot and cold. The four seasons on earth are not only periodic changes in temperature, but also periodic changes in the length of day and night and the height of the sun. It affects or determines the motion rhythm of many things in the Earth's environment, especially biological adaptation.
