50 points as I said◉‿◉​

Answer 1

The Northern Hemisphere spends half the year tilted in the direction of the Sun, getting direct sunlight during long summer days. During the other half of the year, it tilts away from the Sun, and the days are shorter. Winter Solstice, December 21, is the day when the North Pole is most tilted away from the Sun.

Answer 2

Answer:

During the winter solstice, the northern hemisphere is tilted away from the sun in its orbit. Since it is tilted away from the sun, it receives less sunlight, making the day shorter and the night longer.
