Geophysics—an overview
Physics Today 27 (3), 23–26 (1974);
https://doi.org/10.1063/1.3128490
The practitioners of this rich and varied field, which transcends the boundaries dividing scientific disciplines and national interests, have a unique opportunity to serve society.
The Earth's thermal gradient
Physics Today 27 (3), 28–34 (1974);
https://doi.org/10.1063/1.3128491
Modern theories emphasize the importance of mantle convection and recognize the variation in temperature distribution beneath different regions of the globe.
Earthquake prediction
Physics Today 27 (3), 36–42 (1974);
https://doi.org/10.1063/1.3128492
Variations in physical properties such as electrical conductivity and elevation of benchmarks may fortell not just the place but also the time and magnitude of an earthquake.
The interior of the Moon
Physics Today 27 (3), 44–49 (1974);
https://doi.org/10.1063/1.3128493
As a result of the Apollo program we know that the lunar crust is much older than we had suspected, but the interior temperature remains a puzzle, as does the problem of the Moon's origin
