Earth's Engine.

The central theme of this book is plate tectonics. Evidence for plate tectonics, the main forces acting on plates, and the interactions between plates are reviewed. Recent results from seismic tomography are introduced, providing evidence for how the mantle moves. Plate tectonics is the surface manifestation of thermal processes at depth, and the generation and transfer of heat within the Earth, and the response of the lithosphere to thermal and mechanical stress are also covered. This book covers Continental Drift and Plate Tectonics, The Engine's Power Source and Strengths and Weaknesses in the Lithosphere.
