Is the alternation of seasons caused by rotation or revolution?

The four seasons are caused by revolution, because different incident angles of sunlight give different energy to different parts of the earth.

The alternation of the four seasons is more complicated, mainly because the revolution of the earth is different from that of the revolution, that is, the rotation of the earth is inclined, and only in this way will the incidence angles of sunlight in the four seasons be different. In our summer, the sun shines directly into the northern hemisphere, and most of the energy is transferred to the northern hemisphere. This is winter. In spring and autumn, the energy distribution of the sun is relatively uniform, and the temperature difference between the northern and southern hemispheres is not large. In winter, the sun shines directly into the southern hemisphere, and the energy is mainly transferred to the southern hemisphere.

This question is affirmative.
