Origin of the Earth and Moon [Book Review]

Abstract

This small book is divided into three sections containing four chapters each. The three sections are entitled Composition and Constitution of the Earth, Origin of the Earth, and The Moon and Planets. The first four chapters cover the same ground in about the same way as the author's 1975 book, Composition and Petrology of the Earth's Mantle. Most of the figures and tables are taken from the previous publication. The main difference is that Ringwood now believes that the light element in the core is oxygen. He previously argued that it was silicon and, later, sulfur. A major conclusion of the first two-thirds of the book is that the Earth accreted homogeneously.
