In this paper, Custance describes how the geology of the earth may have been formed by continental drift caused by the loss of material from the earth which created the moon and left a void filled by the Pacific Ocean. He believed this hypothesis was too tentative (continental drift had yet to be accepted, and moon rocks were just being analyzed) to be included in the Doorway Papers Series.
