Mariana Trench
The Mariana Trench or Marianas Trench is located in the western Pacific Ocean about 200 kilometres (124 mi) east of the Mariana Islands it is the deepest oceanic trench on Earth. It is crescent-shaped and measures about 2 550 km (1 580 mi) in length and 69 km (43 mi) in width.

How cold is the bottom of ocean?

Therefore the deep ocean (below about 200 meters depth) is cold with an average temperature of only 4°C (39°F). Cold water is also more dense and as a result heavier than warm water. Colder water sinks below the warm water at the surface which contributes to the coldness of the deep ocean.

Does the ocean 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.

What is underneath 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.

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.

What lives at the bottom of the ocean?

Many bottom-dwellers and deep-sea creatures must adapt to their dark often frigid environments in order to survive.

Are there plants in the deep ocean?

Deep in the ocean the pressure is high and the temperatures are low. However plants and animals can still thrive in those places that were once seen as impossible for sustaining life. Far fewer varieties of plants live in the deep ocean compared to shallower waters that receive more sunlight.

Is there life in the deepest part of the ocean?

The organisms discovered in the Mariana Trench include bacteria crustaceans sea cucumbers octopuses and fishes. In 2014 the deepest living fish at the depth of 8000 meters Mariana snailfish was discovered near Guam. … Fish living closer to the surface of the ocean may have a swim bladder filled with air.

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.

What is the coldest place on Earth?

Oymyakon is the coldest permanently-inhabited place on Earth and is found in the Arctic Circle’s Northern Pole of Cold.

Why is the ocean 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.

How cold is the moon?

The average temperature on the Moon (at the equator and mid latitudes) varies from -298 degrees Fahrenheit (-183 degrees Celsius) at night to 224 degrees Fahrenheit (106 degrees Celsius) during the day.

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 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 Earth would look if the oceans drained away?

Why is the ocean salty?

Ocean salt primarily comes from rocks on land and openings in the seafloor. … Rocks on land are the major source of salts dissolved in seawater. Rainwater that falls on land is slightly acidic so it erodes rocks. This releases ions that are carried away to streams and rivers that eventually feed into the ocean.

What youngest part of the ocean floor is found?

mid-ocean ridges

Is there rock under the ocean?

The ocean floor itself is made of mafic rocks the crystallized matter from silicate magma. … Minerals found under the seabed include gabbro basalt serpentine peridotite olivine and ore minerals from VMS.

Why can’t we get to the bottom of the ocean?

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.

How much of Earth is unexplored?

How do creatures survive in the deep sea?

Most of the deep-sea creatures live thousands of feet below the water surface. … These creatures have several adaptations like compressible lungs lung-like swim bladders etc. to help them overcome the high water pressure in their deep-water environment.

How does the ocean refresh itself?

In the open seas water in the sunlit zone receives lots of sun and has a higher temperature than the water below. Under normal condition the process of “upwelling” brings cooler water from down below towards the top. … The supply of nutrient rich cold water to the sunlit zone is critical in maintaining healthy oceans.

What eats kelp in the ocean?

Purple sea urchins eat kelp at their holdfasts (the parts that attach kelp to the bottom). They can reproduce very quickly. In the north Pacific the sea otter is the main and only predator of kelp. On the California current sheephead and spiny lobsters eat kelp too along with the sea otters.
