The Summer Sun
During the summer months, the Sun’s position in the sky brings warm weather, long days, and short nights. Earth’s surface and atmosphere warm up because they receive more heat from the Sun.
In summer, the Sun appears high in the sky and is up longer. Its light falls to the surface at a very steep angle on the half of Earth that is tipped toward the Sun.
The Winter Sun
In the winter, the Sun’s position in the sky brings cooler weather, with short days and long nights. Earth’s surface and atmosphere cool down because they get less heat from the Sun.
The winter Sun appears low in the sky during the day on the half of Earth that is tipped away from the Sun. Sunlight streams to the surface at a very shallow angle.
