I've heard that the'sunset' phenomenon is a natural phenomenon. Can you tell me more about it?

The sunset phenomenon refers to the gradual fading of light and color from the sky during sunset, which occurs due to the Earth's rotation. As the sun moves lower in the sky, its rays become increasingly oblique, resulting in less direct illumination of objects on the ground. This causes the sky to take on a reddish-orange tint as the sunlight gradually fades away.
