Winter

Winter – The coldest period on the year.

The temperature can get below minus 40 – 50 celsius (- 40 fahrenheit) in Siberia, Russia.(1) At the winter solstice*, the days are shorter then on the summer and some parts like in the north of Sweden, the sun does not go over the horizon so it will be completely dark. (2)

When it is winter in the northen part of the planet its is summer in the southern part on the planet.

*The earth’s axis tilt so that the northen part of earth will ge short days but long nights.
