The bottom of the deep sea has several features that contribute to the diversity of this habitat The main features are mid-oceanic ridges, hydrothermal vents, mud volcanoes, seamounts, canyons and cold seeps Carcasses of large animals also contribute to habitat diversityThe bottom of the deep sea has several features that contribute to the diversity of this habitat The main features are mid-oceanic ridges, hydrothermal ventshydrothermal ventsA black smoker or deep sea vent is a type of hydrothermal vent found on the seabed, typically in the bathyal zone (with largest frequency in depths from 2500 m to 3000 m), but also in lesser depths as well as deeper in the abyssal zone They appear as black, chimney-like structures that emit a cloud of black material https://enwikipediaorg › wiki › Hydrothermal_vent

What is at the very bottom of the ocean?
In the Pacific Ocean, somewhere between Guam and the Philippines, lies the Marianas Trench, also known as the Mariana Trench At 35,814 feet below sea level, its bottom is called the Challenger Deep — the deepest point known on Earth Challenger Deep is the deepest point of the Marianas Trench
What’s at the bottom of the deepest ocean?
Toward the southern end of the Mariana Trench lies the Challenger Deep It sits 36,070 feet below sea level, making it the point most distant from the water’s surface and the deepest part of the Trench Don Walsh reached the Challenger Deep in a US Navy submersible
Does the sea have a bottom?
The seabed (also known as the seafloor, sea floor, ocean floor, and ocean bottom) is the bottom of the ocean All floors of the ocean are known as ‘seabeds’ The structure of the seabed of the global ocean is governed by plate tectonics Most of the ocean is very deep, where the seabed is known as the abyssal plain
Can we reach the bottom of the ocean?
The deepest point ever reached by man is 35,858 feet below the surface of the ocean, which happens to be as deep as water gets on earth To go deeper, you’ll have to travel to the bottom of the Challenger Deep, a section of the Mariana Trench under the Pacific Ocean 200 miles southwest of Guam
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
Has anyone been to bottom of 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
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
Who owns the ocean floor?
The oceans have no apparent surface features — just a flat, vast, briny expanse They’re also all connected; the world’s five oceans are technically one single ocean that covers 71 percent of the planet [source: NOAA] This makes it difficult to divide, and so ultimately, you own the oceans
What is under the deep sea?
The abyssal plain is the relatively level deep seafloor It is a cold and dark place that lies between 3,000 and 6,000 meters below the sea surface It is also home to squat lobsters, red prawns, and various species of sea cucumbers For these creatures food is scarce most of the time
What happens to a human body at the bottom of the ocean?
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 much of the earth is still 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
Why havent we reached the bottom of the ocean?
“The intense pressures in the deep ocean make it an extremely difficult environment to explore” “On a dive to the bottom of the Mariana Trench, which is nearly 7 miles deep, you’re talking about over 1,000 times more pressure than at the surface,” Feldman said
How deep can you go in the ocean without dying?
For most swimmers, a depth of 20 feet (609 metres) is the most they will free dive Experienced divers can safely dive to a depth of 40 feet (1219 metres) when exploring underwater reefs When free diving the body goes through several changes to help with acclimatisation
What is the black demon?
The Black Demon is said to be between 20-60 feet long and weighing anywhere between 50-100,000 lbs It is said to resemble a great white shark but with very dark coloration and a large tail Some say it could be the Megalodon or a new species of shark, or perhaps an unusually large Great White
Are there monsters in the Mariana Trench?

What killed the megalodon?
We know that megalodon had become extinct by the end of the Pliocene (26 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
Has any human visited the Mariana Trench?
The first and only time humans descended into the Challenger Deep was more than 50 years ago In 1960, Jacques Piccard and Navy Lt Don Walsh reached this goal in a US Navy submersible, a bathyscaphe called the Trieste
