Why does the Sun appear reddish early in the morning?

Explanation

- The Earth rotates on its axis, and as it does, different parts of the Earth face the Sun at different times. In the morning, the part of the Earth facing the Sun is transitioning from night to day.

- At sunrise (and sunset), the Sun is at a low angle in the sky. The sunlight has to travel through a greater thickness of the Earth's atmosphere compared to when the Sun is directly overhead at noon.
