Knowledge of geography. What is the changing rule of the shadow length of objects in spring, summer, autumn and winter? Help me to be more specific, thank you!

In a year, the sun shadows in different seasons are different, and the length of the sun shadows at different times of the day is also different. The sun shadows at different latitudes at the same time in the same season are also different. It is necessary to analyze specific problems. In a day, the shadow is the shortest at noon, and the length of the shadow increases gradually from noon to sunrise and sunset. As far as the season is concerned, the upstairs has already said it. In short, the southern hemisphere is a summer half year, especially in summer and winter solstice, and its sun shadow is short, and vice versa. I won't go into details. In latitude, the closer to the latitude of the sun's direct point, the shorter the sun shadow. On the contrary, the longer the time. Many of these problems are related to life experiences. Can only say that your life experience is too lacking.
