Why is the earth warmer than the moon?

Answer 1

That's not necessarily a true blanket statement.

The surface temperature at various places on the earth ranges between, let's say,

-100 to +120 Fahrenheit (-88 to +50 Celsius).

On the moon, the surface temperature on the 'night' side is about -240 F (-150 C), but

on the 'day' side, it's about +225 F (+105 C) ... hotter than boiling water.

The earth's atmosphere absorbs heat from the sun and distributes it around the planet.

With no atmosphere on the moon, the surface takes full heat of the sun when the sun is up,

and radiates it all away into space when the sun is down.

Answer 2

The Earth is warmer than the Moon because it has a thicker atmosphere that traps heat from the sun. The Moon has no atmosphere to retain heat, so its surface temperature can vary widely between extreme highs and lows. Additionally, the Earth's surface also absorbs and retains heat better due to its composition and geological activity.

Answer 3

Both bodies are at the same distance from the Sun but, unlike the moon, the Earth has an atmosphere.

The atmosphere help retain heat and to spread it across the planet.
