View submission: Why does it get cold at night ?

Heat is constantly being radiated away from the planet. During the day, this is replaced by "new" heat absorbed from the Sun.

At night the Sun is no longer shining on this part of the planet so heat continues to be lost but not replenished by then Sun.

Clouds (water) help retain heat, which explains why on a cloudy night it doesn't cool down as much. On a clear night we get much colder temperatures as more energy is lost.
