What part of the ocean is the deepest?
the Mariana Trench
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.
Has anyone ever reached the bottom of the ocean?
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.
How deep is the Marianas Trench in KM?
It is crescent-shaped and measures about 2,550 km (1,580 mi) in length and 69 km (43 mi) in width. The maximum known depth is 10,984 metres (36,037 ft) (± 25 metres [82 ft]) (6.825 miles) at the southern end of a small slot-shaped valley in its floor known as the Challenger Deep.
How deep can a human dive before being crushed?
Human bone crushes at about 11159 kg per square inch. This means we’d have to dive to about 35.5 km depth before bone crushes. This is three times as deep as the deepest point in our ocean.
How much of the ocean is discovered?
According to the National Ocean Service, it’s a shockingly small percentage. Just 5 percent of Earth’s oceans have been explored and charted – especially the ocean below the surface. The rest remains mostly undiscovered and unseen by humans.
What killed megalodon?
We know that megalodon had become extinct by the end of the Pliocene (2.6 million years ago), when the planet entered a phase of global cooling. It may also have resulted in the megalodon’s prey either going extinct or adapting to the cooler waters and moving to where the sharks could not follow.
Why is the ocean blue?
The ocean is blue because water absorbs colors in the red part of the light spectrum. Like a filter, this leaves behind colors in the blue part of the light spectrum for us to see. The ocean may also take on green, red, or other hues as light bounces off of floating sediments and particles in the water.
What is the deepest and darkest area of the ocean?
The area of the ocean that extends from the low-tide line out to the edge of the continental shelf. Open-ocean zone The deepest, darkest area of the ocean beyond the edge of the continental shelf.
What is the creature living the deepest in the ocean?
In the crushing depths of the ocean, scientists have discovered a species of fish that thrives deeper than any other. The Mariana snailfish has been observed at depths of 8,178 metres – just over 5 miles down. The fish is named after its home, the Mariana Trench in the western Pacific Ocean, which is the deepest part of the world’s seas.
What is the deepest known portion in the ocean floor?
The Mariana trench is the deepest known oceanic floor; at a maximum known depth of 37,070 feet ( +/- 130 feet).
What is the deepest known Ocean in the universe?
Thanks to modern science and improvement exploration vehicles, one of the most obvious has been tackled – which is the mystery of where the deepest ocean in the world lies. This is none other than the Pacific Ocean, which averages approximately 4,280 meters (14,042 ft) in depth and contains the deepest known part of any ocean – the Mariana Trench.
