The seasons are caused by the annual
motion of the sun around the earth!!
Gen 8:22 While the earth remaineth,
seedtime and harvest, and cold and
heat, and summer and winter, and
day and night shall not cease.

The sun follows a clockwise ( East to West ) spiral orbit around a stationary Earth. Complete orbit time is 24 hours.
In addition to orbiting the stationary earth every 24 hours, the sun also follows a spiral orbit from north to south each year. That is what gives us the 4 seasons.
Equinoxes, solstices, and tropics are the result of the north-south motion of the sun, starting with the vernal or spring equinox on March 21, the official beginning of spring in the northern hemisphere.
On that day, the sun lies on the celestial equator. The word equinox refers to the fact that, on this day, the night is equal to the day: each is twelve hours long. The sun is directly above the equator, so its rays fall vertically down.
Through March, April, and May, the sun moves north. On June 22, it reaches its most northerly point, 23 1/2° above the equator. In the northern hemisphere that day is called the summer solstice. It is the longest day of the year and the official beginning of summer. The sun lies on the circle of the earth called the Tropic of Cancer.

On September 23, the sun, moving south, reaches the equator again. The day is again 12 hours long. That day is called the autumnal equinox and is the official beginning of autumn. On December 22, the sun reaches its most southerly point. That day is called the winter solstice and is the official beginning of winter. The sun shines up from beneath the equator. At noon the sun is straight overhead at points on the earth's Tropic of Capricorn, 23 1/2° south of the equator. At that time, it is the summer solstice in the southern hemisphere.
The cycle again repeats itself giving us our 4 seasons and the solar year.
The winter solstice occurs on June 22 in the southern hemisphere.
The annual north-south motion of the sun gives us our four seasons.
