Where is the Peru-Chile Trench located?

Where is the 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.

Why is the Peru-Chile Trench located where it is?

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.

What trench is off the coast of Chile?

Atacama Trench
Depths of the target stations will range between 1,000 – 8,065 m. Atacama Trench, located off the coasts of Peru and Chile, is one of the deepest ocean trenches in the world and has a maximum depth of 8,065 m. It is almost 6,000 kilometers long.

What is happening at the Peru-Chile Trench?

Along the Peru–Chile Trench, that marks the convergence of the oceanic Nazca plate and the continental South America plate (Fig. 1), the occurrence of large magnitude earthquakes is frequent. The Nazca plate is subducting beneath the South America plate with a convergence speed that varies from north to south.

How long is Peru-Chile trench?

approximately 3,666 miles
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 far down does the Mariana Trench go?

7 miles
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 old is 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.

How wide is Chile’s widest point?

350 km
1. Chile is the longest country in the world that stretches from North to South in a narrow strip. The South American country stretches over a length of 4,300 km/ 2,670 miles and has a maximum width of 350 km/ 217 miles at its widest point.

What is the depth of the Peru and Chile Trench?

The Peru–Chile Trench, also known as the Atacama Trench, is an oceanic trench in the eastern Pacific Ocean, about 160 kilometres (99 mi) off the coast of Peru and Chile. It reaches a maximum depth of 8,065 m (26,460 ft) below sea level in Richards Deep (23°10′45″S 71°18′41″W

Where was the Atacama Trench in the Pacific Ocean?

See Article History. Alternative Title: Atacama Trench. 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.

Which is the longest trench in the world?

deep-sea trench: Types. The longest trench is the Peru-Chile Trench, which extends some 5,900 km (about 3,700 miles) along the west coast of South America. Trenches are relatively narrow, usually less than 100 km (about 60 miles) wide.….

Why was there a trench in South America?

The trench delineates the boundary between the subducting Nazca Plate and the overriding South American Plate . 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.
