  2. Plate tectonics - Wikipedia

    en.wikipedia.org/wiki/Plate_tectonics

    The development of the theory of plate tectonics was the scientific and cultural change which occurred during a period of 50 years of scientific debate. The event of the acceptance itself was a paradigm shift and can therefore be classified as a scientific revolution, [47] now described as the Plate Tectonics Revolution.

  3. Vine–Matthews–Morley hypothesis - Wikipedia

    en.wikipedia.org/wiki/Vine–Matthews–Morley...

    The Vine–Matthews–Morley hypothesis, also known as the Morley–Vine–Matthews hypothesis, was the first key scientific test of the seafloor spreading theory of continental drift and plate tectonics. Its key impact was that it allowed the rates of plate motions at mid-ocean ridges to be computed.

  4. Continental drift - Wikipedia

    en.wikipedia.org/wiki/Continental_drift

    The theory of continental drift has since been validated and incorporated into the science of plate tectonics, which studies the movement of the continents as they ride on plates of the Earth's lithosphere. [2] The speculation that continents might have "drifted" was first put forward by Abraham Ortelius in 1596.

  5. Expanding Earth - Wikipedia

    en.wikipedia.org/wiki/Expanding_Earth

    He considered seafloor spreading at divergent plate boundaries as an effect of it. [26] In his opinion mantle convection as used as a concept in the theory of plate tectonics is physically impossible. His theory includes the effect of solar wind (geomagnetic storms) as cause for the reversals of the Earth magnetic field. The question of mass ...

  6. Seafloor spreading - Wikipedia

    en.wikipedia.org/wiki/Seafloor_spreading

    Plates in the crust of the earth, according to the plate tectonics theory. In the general case, seafloor spreading starts as a rift in a continental land mass, similar to the Red Sea-East Africa Rift System today. [16] The process starts by heating at the base of the continental crust which causes it to become more plastic and less dense.

  7. John Tuzo Wilson - Wikipedia

    en.wikipedia.org/wiki/John_Tuzo_Wilson

    John Tuzo Wilson (October 24, 1908 – April 15, 1993) was a Canadian geophysicist and geologist who achieved worldwide acclaim for his contributions to the theory of plate tectonics. He added the concept of hot spots, a volcanic region hotter than the surrounding mantle (as in the Hawaii hotspot).

  8. Paleomagnetism - Wikipedia

    en.wikipedia.org/wiki/Paleomagnetism

    Evidence from paleomagnetism led to the revival of the continental drift hypothesis and its transformation into the modern theory of plate tectonics. Apparent polar wander paths provided the first clear geophysical evidence for continental drift, while marine magnetic anomalies did the same for seafloor spreading .

  9. Outline of plate tectonics - Wikipedia

    en.wikipedia.org/wiki/Outline_of_plate_tectonics

    Plate tectonics (from Latin tectonicus, from Ancient Greek τεκτονικός (tektonikós) 'pertaining to building') is the scientific theory that Earth's lithosphere comprises a number of large tectonic plates, which have been slowly moving since 3–4 billion years ago.
