This introduction to planetary geology concentrates on the surface features of the planets and satellites of our Solar System. The author first discusses the primary processes that shape our planet, Earth, and the geomorphology of the objects in the Solar System. The second edition includes new information about Venus and a new chapter on Neptune. The book is beautifully illustrated with high-resolution black-and-white photographs from recent space probes and orbiting spacecraft, and with explanatory diagrams. Each chapter starts with a description of the general physiography and terrain units, then the geomorphic processes that created them are discussed. Finally a synopsis of the geologic evolution of the surface is given. The selected references at the end include original papers, review articles and books.
