Question

In the absence of atmosphere, the colour of sky will be

• A. Black
• B. Green
• C. Red
• D. Yellow

Answer 1

The correct option is A Black

An atmosphere is the layer of different gases at different temperatures. The sky appears blue due to the scattering of light by small particles of the atmosphere (air molecules). In the absence of atmosphere, no scattering of light takes place so the sky appears black.

So, the correct answer is option A.
