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.
What's at the bottom of the ocean floor?
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 diversity.

The main reason is deep sea is finite whereas Outer space is infinite. Getting humans down to the deepest areas is exceedingly difficult due to extreme pressures. All that pressure makes deep sea exploration logistically very difficult and extremely dangerous.

Where does the ocean drop off?
Many previously unknown features of the seafloor were discovered. Extending out from a continent’s edge is a gently sloping, shallow area called the continental shelf (F). At the edge of the shelf, the ocean floor drops off in a steep incline called the continental slope (A).

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 is the deepest spot in the ocean?
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.
How dark is the bottom of the ocean?After the aphotic zone, there’s complete darkness. From 1,000 meters below the surface, all the way to the sea floor, no sunlight penetrates the darkness; and because photosynthesis can’t take place, there are no plants, either.
Article first time published onAre there undiscovered sea creatures?
Anywhere from one-third to two-thirds of sea life has not been discovered yet, by their estimate. Most of those hidden sea creatures are probably crustaceans, mollusks, worms and sea sponges, they said. The new database, called the World Register of Marine Species (WoRMS), fulfills deep human curiosity, Appeltans said.

Yet, one of the last unknown frontiers – and one of the most deceptively familiar – is on our very own planet. More than 80% of the ocean remains unexplored. And because it’s difficult to protect what we don’t know, only about 7% of the world’s oceans are designated as marine protected areas (MPAs).

What would happen to a human 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.
What is the ocean floor made of?
Oceanic crust is about 6 km (4 miles) thick. It is composed of several layers, not including the overlying sediment. The topmost layer, about 500 metres (1,650 feet) thick, includes lavas made of basalt (that is, rock material consisting largely of plagioclase [feldspar] and pyroxene).
Why are there straight lines on the ocean floor?
These lines are artifacts of the ocean floor mapping process. Oceanographers use sonar—sound waves—to map the ocean bottom. These sonar readings are typically taken by ships towing submersible devices that send out sound waves.
What youngest part of the ocean floor is found?
The youngest crust of the ocean floor can be found near the seafloor spreading centers or mid-ocean ridges. As the plates split apart, magma rises from below the Earth’s surface to fill in the empty void.
Why the ocean is 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.
Do oceans have black holes?
Known as black holes of the ocean, ocean eddies trap water like black holes suck up light in space. … They act as a container for the water trapped inside them. Water temperatures and salt content within the eddies can be different from the surrounding 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.
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.

Why is the ocean water green?
