Is the Peru-Chile Trench active?
The Peru-Chile Trench marks the subduction of the Nazca Plate under the South American Plate and lies offshore from an area of active volcanism.
Is the Peru-Chile Trench convergent?
The trench is a result of a convergent plate boundary, where the eastern edge of the oceanic Nazca Plate is being subducted beneath the continental South American Plate.
How deep is the Peru-Chile Trench?
The Peru-Chile Trench, lying off southern Ecuador to central Chile, is interrupted off southern Peru by the northeast-trending Nasca Ridge. North of Nasca Ridge the trench reaches a maximum depth of nearly 6500 m.
What lives in the deepest part of the Mariana Trench?
The three most common organisms at the bottom of the Mariana Trench are xenophyophores, amphipods and small sea cucumbers (holothurians), Gallo said. “These are some of the deepest holothurians ever observed, and they were relatively abundant,” Gallo said.
What caused the Peru-Chile Trench?
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.
What is special about Peru-Chile Trench?
The Peru- -Chile Trench is narrower than other trenches of the Pacific Ocean (64 km in width). It is the deepest trench of the South Pacific Ocean, reaching a maximal depth of 8,065 m. The Peru-Chile Trench was formed by the subduction of the Nazca and Antarctic plates beneath the South American Plate.
What is the longest trench in the ocean?
Then explain to students that the Mariana Trench is the deepest part of the ocean and the deepest location on Earth. It is 11,034 meters (36,201 feet) deep, which is almost 7 miles.
What is the Earth deepest point called?
The Mariana Trench, in the Pacific Ocean, is the deepest location on Earth.
How old is the Peru-Chile Trench?
Nazca-South America convergence over the past 23 million years has created the 6-km-deep Peru-Chile trench, 150 km offshore. High pressure between the plates creates a locked zone, leading to deformation of the overriding plate.
What caused the Peru-Chile trench?
What are the 5 ocean trenches?
The Five Deeps Expedition was the first to reach the deepest point in each of the Earth’s five oceans: the Puerto Rico Trench in the Atlantic, South Sandwich Trench in the Southern Ocean, Java Trench in the Indian Ocean, Challenger Deep in the Pacific and Molloy Deep in the Arctic.
