\sf\large \green{\underbrace{\red{Answer⋆}}}:

The sky is everything that lies above the surface of the Earth, including the atmosphere and outer space. In the field of astronomy, the sky is also called the celestial sphere. This is an abstract sphere, concentric to the Earth, on which the Sun, Moon, planets, and stars appear to be drifting.

The upper atmosphere that surrounds the world is known as the sky. The atmosphere filters the sun's white light, removing a bigger part of the blue wavelengths. Your eyes respond to the light waves by registering higher levels of blue light as the blue light is distributed more widely.

Explanation:

  • The term "sky" refers to all that exists above the Earth's surface, including space.
  • That's why the night sky is lit up by so many stars, many of which are similar to our own sun but are much further away.
  • This, like a big greenhouse, keeps the Earth at a reasonable temperature and prevents it from being too cold.
