The Little Book of Planet Earth presents a concise description of the geological evolution of Earth from its formation. Meissner describes in detailed but accessible prose not just the planet's features, but the tools that modern geologists use to explore and track the ever-changing subterranean and surface features of the planet. With a particular gift for expressing how the forces in and around our planet constantly alter the world we live in, the author introduces lay readers to the key topics in modern earth and planetary science: the creation of Earth and its moon (as well as stars and other planets), the role of seismology in analyzing Earth's structure, the formation of mountain ranges and basins, the role of plate tectonics, the significance of Earth's magnetic field, and the complex relationship of our planet's geology to the life forms found there.

This is an EXACT reproduction of a book published before 1923. This IS NOT an OCR'd book with strange characters, introduced typographical errors, and jumbled words. This book may have occasional imperfections such as missing or blurred pages, poor pictures, errant marks, etc. that were either part of the original artifact, or were introduced by the scanning process. We believe this work is culturally important, and despite the imperfections, have elected to bring it back into print as part of our continuing commitment to the preservation of printed works worldwide. We appreciate your understanding of the imperfections in the preservation process, and hope you enjoy this valuable book.

The aim of this book is to develop an integrated and balanced picture of today's knowledge of the continental crust. In this context, geophysical arguments dominate throughout the book; whenever possible, the geophysical parameters are related to geological knowledge and reasoning. Relatively little space is given to detailed mathematical expositions and then only to those topics for which it seemed to be unavoidable.
