    Map showing Earth's principal tectonic plates and their boundaries in detail. These plates comprise the bulk of the continents and the Pacific Ocean.For purposes of this list, a major plate is any plate with an area greater than 20 million km 2 (7.7 million sq mi)

    Limestone pavement – Natural karst landform consisting of a flat, incised surface of exposed limestone. Mesa – Elevated area of land with a flat top and sides, usually much wider than buttes. Mushroom rock – Naturally occurring rock whose shape resembles a mushroom. Natural arch – Arch-shaped natural rock formation.

  4. List of tectonic plate interactions - Wikipedia

    en.wikipedia.org/wiki/List_of_tectonic_plate...

    List of tectonic plate interactions. Tectonic plate interactions are classified into three basic types: [1] Convergent boundaries are areas where plates move toward each other and collide. These are also known as compressional or destructive boundaries. Obduction zones occurs when the continental plate is pushed under the oceanic plate, but ...

    Satellite image of the Tibetan Plateau between the Himalayan mountains to the south and the Taklamakan Desert to the north. In geology and physical geography, a plateau (/ p l ə ˈ t oʊ, p l æ ˈ t oʊ, ˈ p l æ t oʊ /; French:; pl.: plateaus or plateaux), [1] [2] also called a high plain or a tableland, is an area of a highland consisting of flat terrain that is raised sharply above the ...

  6. Plate tectonics - Wikipedia

    en.wikipedia.org/wiki/Plate_tectonics

    Plate tectonics (from Latin tectonicus, from Ancient Greek τεκτονικός (tektonikós) 'pertaining to building') [ 1 ] 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. [ 2 ][ 3 ][ 4 ] The model builds on the concept of continental ...

  7. Abyssal plain - Wikipedia

    en.wikipedia.org/wiki/Abyssal_plain

    v. t. e. An abyssal plain is an underwater plain on the deep ocean floor, usually found at depths between 3,000 and 6,000 metres (9,800 and 19,700 ft). Lying generally between the foot of a continental rise and a mid-ocean ridge, abyssal plains cover more than 50% of the Earth 's surface. [1][2] They are among the flattest, smoothest, and least ...

  8. Oceanic trench - Wikipedia

    en.wikipedia.org/wiki/Oceanic_trench

    Oceanic trenches are prominent, long, narrow topographic depressions of the ocean floor. They are typically 50 to 100 kilometers (30 to 60 mi) wide and 3 to 4 km (1.9 to 2.5 mi) below the level of the surrounding oceanic floor, but can be thousands of kilometers in length. There are about 50,000 km (31,000 mi) of oceanic trenches worldwide ...

  9. Tectonics - Wikipedia

    en.wikipedia.org/wiki/Tectonics

    In plate tectonics, the outermost part of the Earth known as the lithosphere (the crust and uppermost mantle) act as a single mechanical layer. The lithosphere is divided into separate "plates" that move relative to each other on the underlying, relatively weak asthenosphere in a process ultimately driven by the continuous loss of heat from the ...
