Question 40
Why does moon have very cold and very hot temperature variations e.g., from -${190}^{\circ }$C to ${110}^{\circ }$C even though it is at the same distance from the sun as the earth is?

Answer 1

On the surface of the moon, there is no atmosphere, thus the temperature range varies from -${190}^{\circ }$C to ${110}^{\circ }$C. 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.
