Plate tectonics theory
Geometrically precise description of relative motion of lithospheric plates
- Data from Very Long Baseline Array, satellite telemetry, & GPS surveys confirm earth movements consistent with the predictions of plate tectonic theory
Provides rational explanation for the volcanism, plutonism, metamorphism, deformation, & seismicity observed on earth
- Processes concentrated at plate boundaries
- Successfully predicts the relative likelihood of seismic activity, volcanism
- Understand the formation of mountain belts through Wilson cycle; now understand the geology of continents
Plate movement is a process by which heat escapes from earth's interior
