Quick Answer

The sun appears to set when it vanishes over the western horizon as the Earth rotates away from the sun. Depending on the Earth's tilt at a particular time of year, the sun sets either slightly north or south of due west.

Full Answer

During the spring and fall equinoxes, when the tilt of the Earth is level with the sun, the sun sets at exactly due west. When the poles of the Earth are tilted either completely away from or towards the sun, the sun does not appear to set, leading to perpetual night during winter and months-long daylight during the summer.

  • Q:

    Why do humans need light?

    A:

    Light is necessary for the survival of life on Earth, as almost all energy used by life is derived from the sun. Plants and algae use light energy in photosynthesis, which provides usable chemical energy for heterotrophic organisms. In addition, without light, the Earth would be completely cold and dark, as even the moon gets its glow from reflecting the sun.

  • Q:

    Where does the sun rise and set?

    A:

    The sun actually does not rise or set; it is only perceived as rising or setting because of a person's vantage point on the surface of the Earth. This perception of the sun rising and setting is due to the rotation of the Earth itself.
