Why does moon have very cold and very ho | Class 9 Science Chapter Natural Resources, Natural Resources NCERT Solutions

Question:

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:

Atmosphere plays a vital role in climate control and acts as a temperature buffer. It prevents the sudden increase in temperature during the day light hour and slows down the escape of heat into the outer space during night thereby preventing the excessive cooling during the night. In this way, the average temperature of earth remains fairly steady. Although the moon is at the same distance from the sun as the earth is, but since moon has no atmosphere, so the temperature on the surface of moon shows large variations. Moon gets heated up as sun’s rays fall on its surface and it cools down drastically when sun’s rays are not falling over it.
