Because this part of the Earth's orbit, the north part tips away from the sun. the Earth is on quite a slant.

It's because of the tilt of the Earth. On the winter solstice, either the northern or southern hemisphere is tilted slightly away from the sun. This means that the midday sun strikes at a shallow angle, and the length of daylight is not long enough to really heat up the air and ground.



Please read (interesting):

As winter progresses, it actually starts to get darker LATER and the days start getting LONGER. The winter solstice is when we receive the least amount of sunlight. After this day, the length of daylight starts to increase, even though the days are still getting cooler. This is known as "seasonal lag". The same thing happens in the summer. After the summer solstice, the days start growing shorter, even though the hottest weather does not occur until a month or two after the solstice.

The orbit of the earth changes. Sun is closer to the equater. Dec 21 is the night with the longest darkness. After that, earth tilts a bit, each night will be a minute or two shorter, till June 21, when it tilts again, and the process starts over.

It has to do with the positioning of the earth. On Dec 21, the northern part of the earth is tilted away from the sun the most, so that's the day of most darkness.
