What's beneath the ocean floor?The ocean floor is called the abyssal plain. Below the ocean floor, there are a few small deeper areas called ocean trenches. Features rising up from the ocean floor include seamounts, volcanic islands and the mid-oceanic ridges and rises.
Is there a life Under the sea?The deep-ocean floor is teeming with undiscovered life-forms that help to regulate Earth's climate, a new study finds. Researchers sequenced DNA from deep-sea sediments around the world and found that there is at least three times more life on the seafloor than there is higher up in the ocean.
What is found on the sea floor?The seafloor contains deposits of minerals that we we use in everyday life such as copper, zinc, nickel, gold, silver, and phosphorus. These deposits occur as crusts on volcanic and other rocks and as nodules on abyssal plain sediment that are typically about 3 to 10 centimeters (1 to 4 inches) in diameter.

Is there a city under the ocean?Baia, Italy
This submerged underwater city is believed to be the city where not pirates, but hedonistic Romans used to flock to Baia; it was dubbed as the Las Vegas of ancient Rome.
How dark is the bottom of the ocean?Light may be detected as far as 1,000 meters down in the ocean, but there is rarely any significant light beyond 200 meters. The ocean is divided into three zones based on depth and light level.
Are there human bodies in the ocean?Lots of human bodies end up in the sea, whether due to accidents, suicides or from being intentionally dumped there, but nobody really knows what happens to them, said Gail Anderson, a forensic entomologist at Simon Fraser University in Canada who led the unusual study.
Are there monsters at the bottom of the ocean?Creatures that inhabit the abyssal zone include chemosynthetic bacteria, worms, small fish, and certain shark species. Small fish, worms, and certain shark species live in the abyssal zone three miles below the surface.
Can humans live on the ocean floor?The answer to whether we can technically live under the sea is a definite YES, and in fact, Jacques Cousteau and a team of fellow aquanauts lived undersea in Conshelf I, II and III in the early 1960's.

Have humans reached the bottom of the ocean?While thousands of climbers have successfully scaled Mount Everest, the highest point on Earth, only two people have descended to the planet's deepest point, the Challenger Deep in the Pacific Ocean's Mariana Trench.
Why can't we go to the bottom of the ocean?“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.
How deep can a human go in the ocean?The maximum depth reached by anyone in a single breath is 702 feet (213.9 metres) and this record was set in 2007 by Herbert Nitsch. He also holds the record for the deepest dive without oxygen – reaching a depth of 831 feet (253.2 metres) but he sustained a brain injury as he was ascending.
Why is only 5 of the ocean explored?Another reason for the relatively small amount of ocean we have explored is that, at great depths, exploration conditions become extreme. The so-called “sunlight zone” ends at about 200 meters below the surface, making imaging much trickier, and pressure is extremely high.
What lives in deepest part of the ocean?The three most common organisms at the bottom of the Mariana Trench are xenophyophores, amphipods and small sea cucumbers (holothurians), Gallo said. "These are some of the deepest holothurians ever observed, and they were relatively abundant," Gallo said.
What do scientists think is at the bottom of the ocean?In addition to minerals, we've found unusual animals at the bottom of the ocean. Smithsonian points out that even at 13,000 feet below the surface, where temperatures are near freezing and there's no sunlight, researchers have discovered living creatures such as fish, coral, crustaceans, jellyfish and worms.
Is there a hidden city in the ocean?One kilometre out in the Mediterranean Sea, near Haifa, Israel, an ancient village lies hidden beneath the waves. It has been so well preserved by the sandy seabed that weevils sit in the grain stores, human skeletons lie undisturbed in their graves, and a mysterious stone circle still stands as it was first erected.
What city sank into the ocean?Pavlopetri is thought to be the oldest underwater city in history. Located on the southern coast of Lakonia in Greece, the flooding of the city is said to have taken place around 5,000 years ago. It's been an archaeological site of great value since it was discovered in 1967.
