The earth orbits around the sun once a year. As it does, day by day, our planet experiences a variety of changes in the weather. The cold months of winter weather slowly come to an end as the air begins to warm and it becomes spring. These cool spring conditions continue to change into even warmer, summer weather. Eventually, the air begins to turn cooler as the autumn months commence. A few months later, winter has inevitably returned. Why do the seasons change as the earth orbits around the sun?

The winter solstice is the shortest day and longest night of the year in the Northern Hemisphere. The winter solstice is marked by the point at which the North Pole is at its farthest from the sun during its yearly orbit around the sun. It will be approximately 23 degrees away from the sun.
