For this question : How does the photoperiod differ between the two solstices?

wouldn't the solstices be spring and fall?

The overall photoperiod doesn't differ in the summer-fall season and the winter-spring season.

On June 22, the days begin getting shorter in the Northern Hemisphere. The day length is the shortest at the end of the fall season on December 21. They begin getting longer on December 22 and continue getting longer until June 21.

The summer solstice in the Northern Hemisphere is around June 21 and is the beginning of summer. The winter solstice is about December 21 and is the beginning of winter.

The question is asking how the photoperiod is different between the summer-fall period and the winter-spring period.

In the summer-fall period we experience the longest photoperiod of the year. During the winter-spring period we experience the shortest photoperiod of the year.

Is this right? I don't really get it:-(

oh, I see, thank you :-)

You're welcome, Sara.

Actually, the solstices refer to two specific points in the Earth's orbit around the Sun when the tilt of Earth's axis is at its maximum – the summer solstice and the winter solstice. The summer solstice occurs around June 21st in the Northern Hemisphere and around December 21st in the Southern Hemisphere. On the summer solstice, the Northern Hemisphere experiences its longest day of the year, with the most sunlight and the shortest night. Conversely, the winter solstice occurs around December 21st in the Northern Hemisphere and around June 21st in the Southern Hemisphere. On the winter solstice, the Northern Hemisphere experiences its shortest day with the least sunlight and the longest night.

Regarding the photoperiod, which refers to the duration of time each day when there is light, the solstices mark important changes. During the summer solstice, the photoperiod is at its maximum in the Northern Hemisphere, meaning there are more hours of daylight and less darkness. On the other hand, during the winter solstice, the photoperiod is at its minimum, with fewer hours of daylight and more hours of darkness. The opposite occurs in the Southern Hemisphere, where the winter solstice corresponds to the maximum photoperiod, and the summer solstice corresponds to the minimum photoperiod.
