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.
Where is Peru-Chile Trench located?
map. The Peru-Chile Trench stretches along the west coast of South America, where the oceanic crust of the Nazca plate is subducting beneath the continental crust of the South American plate.
Is the Peru-Chile Trench active?
Most of these earthquakes occur along the Peru–Chile Trench, one of the most seismically active subduction zones of the world.
What boundary is the Peru-Chile Trench?
Geology. 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.When did the Peru-Chile Trench form?
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 Mariana Trench?
The Mariana Trench was formed through a process called subduction. Earth’s crust is made up of comparably thin plates that “float” on the molten rock of the planet’s mantle. … This movement creates a trench where the descending oceanic plate drags down the edge of the overriding plate.
How far down does the Mariana Trench go?
It is 11,034 meters (36,201 feet) deep, which is almost 7 miles. Tell students that if you placed Mount Everest at the bottom of the Mariana Trench, the peak would still be 2,133 meters (7,000 feet) below sea level.

How many plates lie under the Pacific Ocean?Tectonic plates map showing the Ring of Fire The Earth is always on the move due to the motion of the tectonic plates. Seven of the major plates make up most of the seven continents and the Pacific Ocean.
Article first time published onWhat animals live in the Peru-Chile Trench?
The expedition to the Peru-Chile trench in the South East Pacific Ocean revealed a new species of snailfish living at 7000m, never before caught or captured on camera. Mass groupings of cusk-eels and large crustacean scavengers were also discovered living at these depths for the first time.
Where is the deepest part of the ocean?
The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam. Challenger Deep is approximately 36,200 feet deep.
What could possible happen if a continental plate collides with oceanic plate?
When an oceanic and a continental plate collide, eventually the oceanic plate is subducted under the continental plate due to the high density of the oceanic plate. Once again a benioff zone forms where there are shallow intermediate and deep focus earthquakes.
How deep is the Peru trench?
It reaches a maximum depth of 26,460 feet (8,065 m) below sea level in Richards Deep and is approximately 3,666 miles (5,900 km) long; its mean width is 40 miles (64 km) and it covers an expanse of some 228,000 square miles (590,000 square km).
How deep is the Puerto Rican trench?
According to NOAA: The deepest part of the Puerto Rico Trench is just over 8,600 meters (5.3 miles).
What tectonic plate is Peru on?
The ongoing subduction, along the Peru–Chile Trench, of the Nazca Plate under the South American Plate is largely responsible for the Andean orogeny. The Nazca Plate is bounded on the west by the Pacific Plate and to the south by the Antarctic Plate through the East Pacific Rise and the Chile Rise respectively.
Are there monsters in the Mariana Trench?
Despite its immense distance from everywhere else, life seems to be abundant in the Trench. Recent expeditions have found myriad creatures living out their lives at the bottom of the sea-floor. Xenophyophores, amphipods, and holothurians (not the names of alien species, I promise) all call the trench home.
What would happen to a human at the bottom of the Mariana Trench?
The pressure from the water would push in on the person’s body, causing any space that’s filled with air to collapse. (The air would be compressed.) So, the lungs would collapse. … The nitrogen would bind to the parts of the body that need to use oxygen, and the person would literally suffocate from the inside out.
How deep can humans go in the ocean?
How deep in the ocean can the human body go? That means that most people can dive up to a maximum of 60 feet safely. For most swimmers, a depth of 20 feet (6.09 metres) is the most they will free dive. Experienced divers can safely dive to a depth of 40 feet (12.19 metres) when exploring underwater reefs.
Can humans go to the Mariana Trench?
While thousands of climbers have successfully scaled Mount Everest, the highest point on Earth, only two people have descended to the planet’s deepest point, the Challenger Deep in the Pacific Ocean’s Mariana Trench.
Who went to the bottom of the Mariana Trench?
On 23 January 1960, two explorers, US navy lieutenant Don Walsh and Swiss engineer Jacques Piccard, became the first people to dive 11km (seven miles) to the bottom of the Mariana Trench. As a new wave of adventurers gear up to repeat the epic journey, Don Walsh tells the BBC about their remarkable deep-sea feat.
Is there deeper than Mariana Trench?
Originally Answered: Is there a place deeper than the Mariana Trench? Yes, but you can’t go there. It’s only 9 inches wide. It’s the Kola Superdeep Borehole, 12,262 meters deep, around 1300m deeper than the Challenger Deep in the Mariana Trench.
What is Richards deep?
a deep-sea trench in the eastern Pacific Ocean, stretching parallel to the South American continent for about 1,500 km. Its eastern slope is considerably steeper and higher than its western slope.
What is the capital of Chile?
The city was only slightly damaged during the War of Independence (1810–18), since the decisive Battle of Maipú took place west of the city limits. Santiago was named the republic’s capital in 1818, and thereafter the wealth of the nation flowed into the city. Santiago, Chile.
How steep is the continental shelf?
It is gently inclined seaward at an average slope of about 0.1°. In nearly all instances, it ends at its seaward edge with an abrupt drop called the shelf break.
