  2. Plate tectonics - Wikipedia

    en.wikipedia.org/wiki/Plate_tectonics

    Plate motions range from 10 to 40 millimetres per year (0.4 to 1.6 in/year) at the Mid-Atlantic Ridge (about as fast as fingernails grow), to about 160 millimetres per year (6.3 in/year) for the Nazca plate (about as fast as hair grows). [9] [10]

  3. North American plate - Wikipedia

    en.wikipedia.org/wiki/North_American_Plate

    The North American plate is a tectonic plate containing most of North America, Cuba, the Bahamas, extreme northeastern Asia, and parts of Iceland and the Azores.With an area of 76 million km 2 (29 million sq mi), it is the Earth's second largest tectonic plate, behind the Pacific plate (which borders the plate to the west).

  4. Mantle convection - Wikipedia

    en.wikipedia.org/wiki/Mantle_convection

    On a global scale, surface expression of this convection is the tectonic plate motions and therefore has speeds of a few cm per year. [15] [16] [17] Speeds can be faster for small-scale convection occurring in low viscosity regions beneath the lithosphere, and slower in the lowermost mantle where viscosities are larger. A single shallow ...

  5. Australian plate - Wikipedia

    en.wikipedia.org/wiki/Australian_Plate

    The northwards collision of the Australian plate with the Sunda plate (Sundaland plate, previously classified as part of Eurasian plate) has a maximum convergence velocity of 7.3 cm (2.9 in) per year ± 0.8 cm (0.31 in) per year at the Java Trench decreasing to 6.0 cm (2.4 in) ± 0.04 cm (0.016 in) per year at the southern Sumatra Trench.

  7. Antarctic plate - Wikipedia

    en.wikipedia.org/wiki/Antarctic_Plate

    The Antarctic plate is a tectonic plate containing the continent of Antarctica, the Kerguelen Plateau, and some remote islands in the Southern Ocean and other surrounding oceans. After breakup from Gondwana (the southern part of the supercontinent Pangea ), the Antarctic plate began moving the continent of Antarctica south to its present ...

  8. Outline of plate tectonics - Wikipedia

    en.wikipedia.org/wiki/Outline_of_plate_tectonics

    Where the plates meet, their relative motion determines the type of plate boundary (or fault): convergent, divergent, or transform. The relative movement of the plates typically ranges from zero to 10 cm annually. Faults tend to be geologically active, experiencing earthquakes, volcanic activity, mountain-building, and oceanic trench formation.
