  2. Plate tectonics - Wikipedia

    en.wikipedia.org/wiki/Plate_tectonics

    On 8 September 2014, NASA reported finding evidence of plate tectonics on Europa, a satellite of Jupiter—the first sign of subduction activity on another world other than Earth. [110] Titan, the largest moon of Saturn, was reported to show tectonic activity in images taken by the Huygens probe, which landed on Titan on January 14, 2005. [111]

  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. Rare Earth hypothesis - Wikipedia

    en.wikipedia.org/wiki/Rare_Earth_hypothesis

    Evidence for the past existence of plate tectonics on planets like Mars [144] which may never have had a large moon would counter this argument, although plate tectonics may fade anyway before a moon is relevant to life. [141] [142] Kasting argues that a large moon is not required to initiate plate tectonics. [87]

  5. Geodynamics of terrestrial exoplanets - Wikipedia

    en.wikipedia.org/wiki/Geodynamics_of_terrestrial...

    Plate tectonics is an efficient method of heat transfer from the interior of the planet to the surface. Earth is the only planet plate tectonics is known to occur on, [6] although evidence has been presented for Jupiter's moon Europa undergoing a form of plate tectonics analogous to Earth's. [7]

  6. Mantle convection - Wikipedia

    en.wikipedia.org/wiki/Mantle_convection

    The lithosphere is divided into tectonic plates that are continuously being created or consumed at plate boundaries. Accretion occurs as mantle is added to the growing edges of a plate, associated with seafloor spreading. Upwelling beneath the spreading centers is a shallow, rising component of mantle convection and in most cases not directly ...

  7. 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.

  8. Fracture zone - Wikipedia

    en.wikipedia.org/wiki/Fracture_zone

    The Heirtzler fracture zone was named after James Ransom Heirtzler, who first demonstrated through magnetostratigraphy that the Mid-Atlantic Ridge was spreading south of Iceland, providing the first clear evidence for plate tectonics. [8] This name was approved by the Advisory Committee on Undersea Features in 1993. [9]

  9. Earth's crustal evolution - Wikipedia

    en.wikipedia.org/wiki/Earth's_crustal_evolution

    Surface map of oceanic crust showing the generation of younger (red) crust and eventual destruction of older (blue) crust. This demonstrates the crustal spatial evolution at the Earth's surface dictated by plate tectonics. Earth's crustal evolution involves the formation, destruction and renewal of the rocky outer shell at that planet's surface.
