Why should there be four seasons in a year?

As we know, there are four seasons in a year: spring, summer, autumn and winter. Their climate

Yes: spring is mild, summer is hot, autumn is cool and winter is cold. There are four seasons in a year, which are caused by the earth turning sideways around the sun. Take a look at the globe. The axis of the center of the earth is not vertical, but inclined. So the place where the sun shines directly is not the equatorial region, but rotates back and forth on both sides of the equator. directsolar radiation

When the temperature in this area is high, it is summer; In winter, the sunshine is the most oblique and the temperature is the lowest; In spring and autumn, the sun is neither direct nor oblique, so the temperature is moderate. This is the difference between the four seasons. If you pay a little attention at ordinary times, you will find that in summer, the sun almost shines from the top of your head; In winter, the sun comes obliquely from the south; In spring and autumn, the sun is straighter than in winter and a little more inclined than in summer.
