Question

Sky appears black in day time if Earth had no atmosphere. Give reason

Answer 1

Answer: The colour of sky will be black if the earth had no atmosphere. This is because due to presence of atmosphere the sun ray get scattered and we see blue sky during the day. In the absence of any atmosphere, there will be no scattering of sunlight and the sky will appear dark.

Answer 2

If earth had no atmosphere, then there would be no gas present in the atmosphere. Since there is no scatterer in the atmosphere of the earth, so there will be no scattering of light. Hence, the sky would appear dark.
