Most of the ocean is undeveloped land.
The ocean is deeper than the highest point on the earth's surface. The
Titanic was at its deepest point, making it the deepest diving mammal Cuvier's beaked whale has ever entered.
But even the wreckage of the Titanic failed to come close to its deepest target, which reached 35,839 feet in 2019.
This magnificent performance shows how deep the ocean is.
How deep is the ocean? If you take the highest point on land and submerge it in water, you are still more than a mile away from the deepest point in the ocean.
The oceans cover 99% of the Earth's surface, enough water to fill a 1085-mile-diameter tub. For comparison, the state of California is approximately 720 miles long.
Overall, the average human is about half the length of the world's largest animal, the blue whale. Blue whales usually hunt in well-lit areas of the ocean at a depth of 100 meters.
Photo of a blue whale swimming underwater has been shown above. 4,444 blue whales can dive to a depth of 1,600 feet. At a depth of 700 feet, the USS Triton became the first submarine to orbit the earth in 1960. At
250 meters, they reached the deepest freedive in history recorded by Austrian-born diver Herbert Nitsch. The pressure here is 26 times that on land, which will make most of humans' lungs collapse. But blue whales can dive to a maximum altitude of 1,640 feet, where they hunt giant squid.
During the descent, Nitsch suffered from severe decompression syndrome, which resulted in multiple strokes. But it surfaced, returned to the hyperbaric chamber, and eventually lived to tell the tale.
At 2,400 feet, we reach the danger zone of modern nuclear attack submarines. Go deep and the lower lid will break.
Burj Khalifa, the tallest building in the world, will reach a height of 722 feet. A little further on, at 3,280 feet, we're too deep for the sun to reach us. We are now in the midnight zone.
Many animals here are invisible, such as the invisible shrimp that thrives near underwater volcanoes at 7,500 feet.

At this depth, the temperature is only a few degrees above freezing, but the water around the hydrothermal vent can warm up to 800 degrees Fahrenheit.
Cuvier's beaked whale swims to a depth of approximately 9,816 feet, making it the deepest swimming animal ever recorded.
But even Cuvier's beaked whale cannot discover the Titanic, which is docked at an astonishing 12,500 feet.
The pressure is now 378 times the ground pressure. But you can still see life like hagfish and Dumbo octopus (the deepest in the world).
The Abyssal Zone is located at 20,000 feet, an area designated as the deepest zone in the ocean, such as the Mariana Trench.
The picture shows how deep the submarine dived into the Mariana Trench compared to where the Titanic was.
Challenger Deep is the deepest place in the world. If Everest
had been dropped into the Mariana Trench, its summit would have reached 29,029 feet. That still doesn't compare to the two deepest programs in history.
In 1960, oceanographers Jacques Piccard and Lieutenant Don Walsh descended into the world's lowest level, the Challenger Deep, at a record depth of 7,979 feet.
They kept this information for years until detective Victor Vescovo arrived in 2019. Vescovo made three Challenger Deep dives that year and set a new record on his third dive, reaching a depth of 35,839 feet.
Scientists sent six unmanned submarines to explore the Challenger Deep, including Kaiko, which collected more than 350 species from the sea between 1995 and 2003. But science researchers estimate that there may be thousands of marine species yet to be discovered.
It is estimated that humans have discovered 5% to 10% of the world's oceans. We are just beginning to understand the deep, dark world that flows under our feet.
