Why is the moon hot during the day and so cold at night?
Since the Moon and the Earth are approximately the same distance from the Sun, they receive sunlight of the same strength. So the temperature of the Earth and the Moon should be the same. It is the Moon’s lack of atmosphere that creates such extreme temperatures. The Moon doesn’t have an atmosphere to absorb sunlight like the Earth does, and so the surface gets very hot. The Moon’s lack of atmosphere also lets heat escape during lunar nights so that it gets rather chilly on the surface!
