fundamental differences resulting from the lack of free water and oxygen on the Moon. The comparison also shows that, while the Moon has been dominated by external processes, the Earth has been dominated by internal processes. The various types of physical and chemical processes represented by the rock cycles, the resulting commercial types of mineral deposits on Earth, and the probable types of lunar deposits are shown in table 4.
