Is Challenger Deep deeper than the Marianas trench?
Were we to stand at the edge of this new Mariana Sea, Challenger Deep would still be 4,924 meters deep—nearly five kilometers, or three miles. So even when drained to the rim of the Mariana Trench, by more than half, Challenger Deep is still deeper than this much of the earth’s oceans .
How far down is the Mariana Trench?
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.
Is Megalodon in the Mariana Trench?
According to website Exemplore: “While it may be true that Megalodon lives in the upper part of the water column over the Mariana Trench, it probably has no reason to hide in its depths. ... However, scientists have dismissed this idea and state that it is extremely unlikely that the megalodon still lives.

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.
Why is the Mariana Trench so deep?
One reason the Mariana Trench is so deep, he added, is because the western Pacific is home to some of the oldest seafloor in the world—about 180 million years old . Seafloor is formed as lava at mid-ocean ridges. When it’s fresh, lava is comparatively warm and buoyant, riding high on the underlying mantle.
How much of the Mariana Trench has been explored?
The Mariana Trench represents just one small part of the Earth’s last, great frontier. Less than five percent of the entire ocean has been explored, yet scientists have found that even the deep sea has great numbers of species—and the discoveries have only just begun.
How do creatures survive in the Mariana Trench?
Under pressure
Fish living closer to the surface of the ocean may have a swim bladder – that’s a large organ with air in it, which helps them float up or sink down in the water. Deep sea fish don’t have these air sacs in their bodies, which means they don’t get crushed.
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.
What is under Mariana Trench?
The Pacific plate is subducted beneath the Mariana Plate, creating the Mariana trench, and (further on) the arc of the Mariana Islands, as water trapped in the plate is released and explodes upward to form island volcanoes and earthquakes.
Is thermocline real?
A thermocline is the transition layer between warmer mixed water at the ocean’s surface and cooler deep water below. ... Below 3,300 feet to a depth of about 13,100 feet, water temperature remains constant.
What fish are in the Mariana Trench?
In the Mariana Trench—7,000 meters below the ocean’s surface—these fish makes a living in total darkness and at crushing pressures that can reach 1,000 times more than at sea level. But the Mariana snailfish is not only abundant in this area; it’s the region’s top predator.
Who killed Megalodon?
— Cold waters may have killed the megalodon shark: Around 3.6 million years ago, as Earth entered a period of global cooling and drying, megalodons went extinct, according to the Natural History Museum.
Are Megalodon’s still alive in 2021?

Guam is the closest land mass to the Mariana Trench, which dips down about 6.8 miles (11 kilometers) below sea level — the deepest point on the planet’s surface.
What formed 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. While floating on the mantle, the edges of these plates slowly bump into each other and sometimes even collide head-on.
Does Kraken exist?
The Kraken Is Real : Scientist Films First Footage Of A Giant Squid For thousands of years, sailors have told stories of giant squids. In myth and cinema, the kraken was the most terrible of sea monsters. Now, it’s been captured — on a soon-to-be-seen video.

How long would it take to swim to the bottom of the Mariana Trench?
First off, nobody could free swim to the “bottom of the ocean.” Two reasons come to mind. First, it takes about four hours to descend in a deep sea submersible to the bottom of the Challenger Deep in the Mariana Trench.

What is the tallest peak in the world?

Why is 95 of the ocean unexplored?
“ The intense pressures in the deep ocean make it an extremely difficult environment to explore.” Although you don’t notice it, the pressure of the air pushing down on your body at sea level is about 15 pounds per square inch. If you went up into space, above the Earth’s atmosphere, the pressure would decrease to zero.
What planet has water besides Earth?
Earth is the only known planet to have bodies of liquid water on its surface. Europa is thought to have subsurface liquid water. Scientists hypothesize that Europa’s hidden ocean is salty, tidal, and causes its ice surface to move, resulting in large fractures which are clearly visible in the above image.
How much of the world’s dry land is unexplored?
The extent of human impact on these underwater ecosystems is impressive. Still, we’ve only mapped 5 percent of the world’s seafloor in any detail. Excluding dry land, that leaves about 65 percent of the Earth unexplored. There’s a lot out there potentially harboring a lot more plastic bags.
