Earth's atmosphere blocks most of the sun's radation but some gets in side of the Atmosphere wisch makes our planet warm. Our atmosphere has a large hole on one of earth's coninents Antartica. The moon does not have a atmosphere so if you dig a hole on the moon it will stay there for thousands of year's.
