Question

In the absence of atmosphere, the colour of the sky would be?

• A. blue
• B. red
• C. white
• D. black

Answer 1

Answer:

D. black

• In the absence of an atmosphere, the sky would appear black, similar to how it looks from space.

• This is because the blue color of the Earth's sky is caused by the scattering of sunlight by molecules in the atmosphere.

• Without an atmosphere, there would be no such scattering, resulting in a dark, black sky.
