Question

If the Earth did not have atmosphere, would its average surface temperature be higher or lower than what it is now? Explain.

Answer in Brief

Solution

If the Earth did not have atmosphere, then there would be absence of greenhouse effect of the atmosphere. Due to this reason, the temperature of the earth would be lower than what it is now.
