Tectonic Consequences of the Earth's Rotation

This book reviews the cumulative evidence for a connection between the Earth's rotation and geotectonics. Satellite and plate-motion data in particular suggest that the rotation affects geotectonics. The author recasts the classical models of body tides and argues that the energy from the tides directs the otherwise random process of convection. Among other benefits, this model could prove an important step in deciphering the flow of the Earth's mantle. Introducing a more complete model of the tidal Earth than those orthodox until now, Bostrom points to the likelihood that a non-reversing term accounts for the remarkable contrast between the Earth and its sister planet Venus--including the existence of mobile plates and the preservation of liquid water.

"This book tries to revive the possibility of a relation between rotation and tectonics by invoking not tidal drag, but the cumulative effect of tidal distortion of the solid Earth. The argument goes as follows. Since the Earth rotates relative to the external potential, the bodily tides should be viewed not as oscillatory spheroidal bulges (as in the classical Darwin-Love-Jeffreys theory), but as 'waves' that travel westwards. . . The author himself states that the book is not intended to prove a connection between the Earth's rotation and geotectonics (but) to review evidence that a connection may exist."--Geoscientist

"The stress ellipsoid emblazoned on the front cover of the book provides a strong hint as to its content, namely the study of the complex effects on the Earth's tectonics of stresses generated by tidal dissipation. . .The book's first two chapters comprise a very readable overview of tidal distortion, true polar wander, a historical perception of Earth rotation and global tectonics. . .The author stated that the book is not intended to prove a connection between the Earth's rotation and geotectonics. Instead it is intended to review evidence that a connection may exist. Despite the undoubtedly difficult nature of the text, in my opinion the book provides a fascinating and generally well written treatise about one of the most intriguing facets of the Earth Sciences."--OUGS Journal
