Answer:
As Earth revolves around the Sun, it rotates on its axis. Sometimes Earth tilts toward the Sun, which is when summer occurs. In the winter, Earth tilts away from the Sun. In North America, around June 21, Earth tilts on its axis toward the Sun.
Winter
- Earth tilts away from the Sun. In North America, around June 21, Earth tilts on its axis toward the Sun. This is called the summer solstice, and it is when the Northern Hemisphere has the most daylight of any time of the year.
