English: How Earth's tectonic plates and lands may have been positioned and moved in the past: an animated video of a full-plate tectonic model extended one billion years into the past. It is a result of the 2020 study "Extending full-plate tectonic models into deep time".
Indo-Australian plate – Major tectonic plate formed by the fusion of the Indian and Australian plates (sometimes considered to be two separate tectonic plates) – 58,900,000 km 2 (22,700,000 sq mi) Australian plate – Major tectonic plate separated from Indo-Australian plate about 3 million years ago – 47,000,000 km 2 (18,000,000 sq mi)
Plate tectonics (from Latin tectonicus, from Ancient Greek τεκτονικός (tektonikós) 'pertaining to building') [1] is the scientific theory that the Earth's lithosphere comprises a number of large tectonic plates, which have been slowly moving since 3–4 billion years ago.
The Pacific plate is moving the fastest at 95 mm/yr NE, then the Cocos plate moving relatively N-NW 67 mm/yr, and 40 mm/yr E –NE for the Nazca plate. [2] Differing border velocities that detect the rate of spreading as well as the lack of/slowing of spreading are also considered as well.
The Himalayan tectonics result in long term deformation. This includes shortening across the Himalayas that range from 900 to 1,500 km. Said shortening is a product of the significant ongoing seismic activity. The continued convergence of the Indian plate with the Eurasian plate results in mega earthquakes.
This paradoxically results in divergence which was only incorporated in the theory of plate tectonics in 1970, but still results in net destruction when summed over major plate boundaries. [2] Divergent boundaries are areas where plates move away from each other, forming either mid-ocean ridges or rift valleys. These are also known as ...
The zone includes most of the islands of Vanuatu, the Santa Cruz islands of the southern Solomon Islands, [4] and the Loyalty Islands.A number of ocean floor features are related to the zone, in particular the New Hebrides Trench (South New Hebridies Trench) [5] and the North New Hebrides Trench (Torres Trench) which is separated from the southern trench by the d'Entrecasteaux Ridge and the ...
Boso triple junction . The Boso triple junction (also known as off-Boso triple junction) is a triple junction off the coast of Japan; it is one of two known examples of a trench-trench-trench triple junction on the Earth (the other being the Banda Sea triple junction).
