I think seasons change because of the Earth's tilt. When it tilts closer to the sun it is

summer and when it the tilt is farther away from the sun it is winter.

Because of the vernel and autumn Equinox the summer winter and autumn solstice.

And also because of the sunrises will change when the seasons start to also change.

But it is mainly all because of the Earth's tilt.
