Peru Chile Trench Ocean Profile
It reaches a maximum depth of 26460 feet 8065 m below sea level in richards deep and is approximately 3666 miles 5900 km long.
Peru chile trench ocean profile. It runs along an oceanic continental boundary where the oceanic nazca plate subducts beneath the continental south american plate. The peruchile trench is located just left of the sharp line between the blue deep ocean on the left and the light blue continental shelf along the west coast of south america. The formation of this trench dates back to the cretaceous era and the subduction that led to the creation of the kuril island arc and the kamchatka volcanic arc.
The peruchile trench also known as the atacama trench is an oceanic trench in the eastern pacific ocean about 160 kilometres off the coast of peru and chile. Profiles across the peru chile trench 247 the writers believe turbidity currents to be the principal agents of sedimentation in the smooth bottomed portions of the peru chile trench. The longest trench known in the world is the peru chile trench which extends to a distance of 5900 km about 3700 miles along the west coast of south america.
Peru chile trench also called atacama trench submarine trench in the eastern pacific ocean about 100 miles 160 km off the coast of peru and chile. Some of the most familiar ocean trenches are the result of this type of convergent plate boundary. The results of the descriptive statistical analysis of the bathymetry in both segments show that the most frequent depths for the peruvian segment of the peru chile trench range from 4000 to 4200 827 recorded samples versus the range of 4500 to 4700 m for the peruvian segment 1410 samples.
Its mean width is 64 km and it covers an expanse of some 590000 km2. The peru chile trench off the west coast of south america is formed by the oceanic crust of the nazca plate subducting beneath the continental crust of the south american plate. These oceanographic features are the deepest parts of the ocean floor.
The trench delineates the boundary between the subducting nazca plate and the overriding south american plate. Today the pacific plate continues to slide under the othotsk plate producing extreme volcanism and seismic activity in the area. Mariana trench also called marianas trench deep sea trench in the floor of the western north pacific ocean the deepest such trench known on earth located mostly east as well as south of the mariana islandsit is part of the western pacific system of oceanic trenches coinciding with subduction zonespoints where two adjacent tectonic plates collide one being forced below the other.
It reaches a maximum depth of 8065 m below sea level in richards deep and is approximately 5900 km long. Oceanic trenches are topographic depressions of the sea floor relatively narrow in width but very long. Canyons and gullies cutting the continental slope in this area offer numerous channels for localized turbidity flows which may have originated at the gully heads as a result of spring floods oa seismic activity.
