Why are the days shorter during the winter solstice?
The hemisphere that is experiencing the winter is tilted away from the sun causing the hemisphere to receive less sunlight and less daylight hours.

500
About how long does it take the Moon to orbit the Earth?
A month
500
Why are days longer during the summer solstice?
The hemisphere that is experiencing the summer is tilted toward the sun causing the hemisphere to receive more sunlight and longer daylight hours.
