The physical make up of our home planet is covered in great depth in this book. The preface gives a brief historical overview of human observation of the skies. It also defines rotation, inclination, obliquity, and the different features of the planets. The chapters deal with the Earth's interior, moment of inertia, the crust, the mantle, rheology, the solid and liquid cores, the magnetic field, temperatures, pressure, composition, the early evolution of the planet, surface features, volcanism, earthquakes, atmosphere, surface conditions, and weather. A special chapter covers the moon and its formation, evolution, crystallization of the Lunar Magma Ocean, meteorite bombardment, fossa, sulci, basins, volcanism, the interior, the surface features, remote sensing, magnetic fields, atmosphere, and missions to the moon. Except for a small block of color photographs in the middle of the book, all the diagrams and photographs are in black-and-white. The type is small but the page design allows for lots of interesting images, diagrams, and charts to add interest.
