In this context, in the 1950s and 60s the new theory of Plate Tectonics was propounded by “Geophysicists” (Physicists) and mainly young Geologists with little experience, depth of understanding or respect for existing geology.

Where the plates meet, their relative motion determines the type of boundary: convergent, divergent, or transform. Earthquakes, volcanic activity, mountain-building, and oceanic trench formation occur along these plate boundaries. The relative movement of the plates typically ranges from zero to 100 mm annually.

Volcanic activity requires a source of internal heat, and it is the escape of this heat that fuels plate tectonics. While volcanism played a major role in the early history of Mars, the Moon, and probably Mercury, their small sizes relative to Earth resulted in the loss of internal heat at a much faster rate.

What was an argument used to dispute the theory of plate tectonics? An argument that was used to dispute the theory of plate tectonics  was the Land Bridge Theory. Land Bridge Theory held that shifting  portions of dry land explained the fin…ding of identical species on  different continents.

However, at the time that Wegener proposed his theory of continental drift, most scientists still believed the Earth was a solid, motionless body. We now know better. As J. Tuzo Wilson eloquently stated in 1968, The earth, instead of appearing as an inert statue, is a living, mobile thing..

All this evidence, both from the ocean floor and from the continental margins, made it clear around 1965 that continental drift was feasible and the theory of plate tectonics, which was defined in a series of papers between 1965 and 1967, was born, with all its extraordinary explanatory and predictive power.

Plate tectonics (from the Late Latin tectonicus, from the Greek: τεκτονικός pertaining to building) is a scientific theory describing the large-scale motion of 7 large plates and the movements of a larger number of smaller plates of the Earth's lithosphere, over the last hundreds of millions of years.

From seismic and other geophysical evidence and laboratory experiments, scientists generally agree with Harry Hess' theory that the plate-driving force is the slow movement of hot, softened mantle that lies below the rigid plates.

The theory of plate tectonics states that the plates of the earth move due to convection in the mantle. This is what brings continents together and apart. Plate Tectonics stat…es that Earth's crust and the outermost part of the mantle are mechanically connected to each other.

Keywords: plate tectonics – alternative geological theories – surge tectonics – wrench tectonics – expansion tectonics – sociology of science. The New Concepts in Global Tectonics Group is an informal association of earth scientists who are critical of plate tectonics and want to explore alternative theories. It arose after a symposium on “Alternative theories to plate tectonics” held at the 30th International Geological Congress (IGC) in Beijing in August 1996.
