Why do seasons change because of the tilt of the earth's axis?
Due to the inclination of the earth's axis, the height angle of the sun varies from place to place at noon every day.
When the solar altitude angle is the largest, the unit area receives more solar radiation, and the local summer is formed when the temperature is the highest in a year; On the contrary, it's winter. The earth completes one cycle after one revolution, and then starts the next cycle.
On the other hand, if the earth's axis is not tilted, the height of the sun at noon is the same every day of the year, the solar radiation received every day is the same, and the temperature is the same, so there is no difference between the four seasons. There is only one season in every place. It is always summer at the equator and within 30 degrees north and south latitude, and it is always winter above 60 degrees north and south latitude.
Supplementary questions are unprofessional. The earth has only one axis. Can it tilt more than two angles? Let's go back and look at the basic knowledge and strengthen the basic skills.
