Early geologists considered that the Earth's surface is rigid and unchanging. They assumed that the whole Earth is static, except for enough sub-surface contraction to build mountains. After seismology developed, most geophysicists agreed. A few scientists, notably Wegener, favoured a more mobile Earth. About 1965 fresh evidence showed that both theories were too simple. This evidence explained why neither theory had been able to relate the whole Earth's behaviour to laws of physics. Hence…

A microseismicity study of the Queen Charlotte Islands region

Nineteen land and three ocean-bottom seismographs were operated in the Queen Charlotte Islands region for periods of up to 9 weeks and 5 days, respectively, during the summer of 1983. Three hundred

On the building and classification of mountains

Physicists believe that known laws should suffice to explain the Earth's behavior, but the complexities of geology have defied simple explanation. Today three developments are helping to solve the

A possible origin of the Hawaiian Islands

It is noted that different physicists and geologists have in recent years espoused not less than four groups of theories of the physical behavior of the Earth's interior. Recent observations of

Convection tectonics: some possible effects upon the Earth's surface of flow from the deep mantle

Until a little more than a century ago the land surface not only was the only part of the Earth accessible to humans but also was the only part for which geophysical and geochemical methods could

Role of the lithosphere in mantle convection

Plate geometry and kinematics generally reflect the mechanical properties of the solid lithosphere rather than those of the fluid mantle underneath, and plate formation and subduction account for

A New Class of Faults and their Bearing on Continental Drift

We derive poloidal flow internal loading Green functions for incompressible fluid models of the mantle consisting either of a single constant viscosity spherical shell or of two adjacent spherical

Theory of Earth

The maturing of the Earth sciences has led to a fragmentation into subdisciplines which speak imperfectly to one another. Some of these subdisciplines are field geology, petrology, mineralogy,

Mantle upflow tectonics in the Canadian Cordillera

A wide variety of geophysical, geological, and petrological results from the Cordillera of western Canada can be related to the history and present tectonics of the region. Southwest of the Rocky
