Why does moon have very cold and very hot temperature variations eg, from -190°C to 110°C even though it is at the same distance from the sun as the earth is?

Answer

Earth has atmosphere which prevents over heating of the earth during day time. On the other hand Moon does not have atmosphere hence it appears to be hotter during day time. Lack of atmosphere in moon also allows the heat to escape during night because of this phenomenon temperature varies on moon surface.
