One of the biggest questions in Geosciences today is "when did plate tectonics begin on Earth" with a wide range of theories based on an equally diverse set of constraints from geology, geochemistry, numerical modeling, or pure speculation. In this contribution, we turn the coin over and ask...

The first question applies to the conventional rigid plate hypothesis Turcotte and Schubert, 1982, Morgan, 1998, as restated in a recent review (Kearey and Vine, 1990, p. 73): “Within the basic theory of plate tectonics, plates are considered to be internally rigid, and MORB recycling, ...
Plate tectonics, theory dealing with the dynamics of Earth’s outer shell that revolutionized Earth sciences by providing a uniform context for understanding mountain-building processes, volcanoes, and earthquakes as well as the evolution of Earth’s sur
Learn about the plate tectonic theory evidence. Discover what the theory of plate tectonics explains about earthquakes and the shapes of the...
Because he came up with the theory of plate tectonics while he was alive, but it was not proven until after his death. Because he was a known crusader for the theory's validity. Because plate tectonics explained his theory on how oceanic ridges formed. ...

Continental drift, large-scale horizontal movement of continents relative to one another and to the ocean basins during one or more episodes of geologic time. This concept was an important precursor to the development of the theory of plate tectonics, wh
