Papallacta, Ecuador on 16 October 2011 The volcano Antisana seen from the hot spring of Papallacta. Papallacta is a village at an altitude of 3,300 metres (10,827 feet) in Napo Province, Ecuador. [1] Its population is 635 as of 2022. [2]
Diagram of a cross-section of the Patagonia slab window. The Nazca plate and Antarctic plate are colliding with the South American plate at the Chile Ridge. [1]In geology, a slab window is a gap that forms in a subducted oceanic plate when a mid-ocean ridge meets with a subduction zone and plate divergence at the ridge and convergence at the subduction zone continue, causing the ridge to be ...
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.
Map showing the location of oceanic plateaus (in green) in the Australia-New Zealand region of the South Pacific. An oceanic or submarine plateau is a large, relatively flat elevation that is higher than the surrounding relief with one or more relatively steep sides.
Obduction is a geological process whereby denser oceanic crust (and even upper mantle) is scraped off a descending ocean plate at a convergent plate boundary and thrust on top of an adjacent plate. [ 1 ] [ 2 ] When oceanic and continental plates converge, normally the denser oceanic crust sinks under the continental crust in the process of ...
The Pacific plate and other principal plates of Earth's lithosphere. The Pacific plate is an oceanic tectonic plate that lies beneath the Pacific Ocean.At 103 million km 2 (40 million sq mi), it is the largest tectonic plate.
Patallacta (possibly from Quechua pata elevated place / above, at the top / edge, bank (of a river), shore, llaqta place (village, town, city, country, nation), [1] "settlement on a platform" [2] pronounced "pahta-yakta"), Llactapata [3] or Q'ente Marka (possibly from Quechua q'inti hummingbird, marka village, "hummingbird village") is an archaeological site in Peru located in the Cusco Region ...
The Nazca plate or Nasca plate, [2] named after the Nazca region of southern Peru, is an oceanic tectonic plate in the eastern Pacific Ocean basin off the west coast of South America. The ongoing subduction , along the Peru–Chile Trench , of the Nazca plate under the South American plate is largely responsible for the Andean orogeny .
