  Why does moon have very cold and very hot temperature variations, e.g., from 190°C to 110°C, even though it is at the same distance from the Sun as the Earth is?

Answer:

                  Absence of atmosphere on the moon has resulted in varying temperature on its surface. The temperature on Earth is maintained by the atmospheric layer around the Earth. It absorbs radiation avoiding overheating and prevents loss of heat from the surface preventing Earth's cooling.
