Which month is the north pole tilted directly toward the sun?

Winter in the Northern Hemisphere begins December 21 or 22, when the North Pole is tilted a full 23.5° away from the sun. This day is known as the winter solstice. The angle of the sun is the lowest and the Northern Hemisphere has the least amount of daylight.

i believe it is "they are not used up by reactions" as the answer to your question, text me back if this is correct because i just learned this.

your spelling is a little off : ]
