About this Book
Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 8.
Geothermal processes play an important role in all theories about the origin, development, and surface features of the Earth. There are several theories as to the source of the distortion of the Earth's crust, which is directly or indirectly thermal in origin: for example, the energy is derived (1) from the contraction of a cooling Earth; (2) from the expansion of a heated Earth; or (3) from convection currents driven by the force of gravity acting on density differences caused by nonuniform temperature distributions. In all these theories, heat flow at the Earth's surface appears as an essential boundary condition.
