, also known as the Mariana Trench. At 35,814 feet below sea level, its bottom is called the Challenger Deep

Challenger Deep

The Challenger Deep is the deepest known point of the seabed in the Earth's hydrosphere (the oceans and seas), with a depth of 10,902 to 10,929 m (35,768–35,856 ft) by direct measurement from deep-diving submersibles, remotely operated underwater vehicles, and benthic landers and (sometimes) slightly more by sonar ...

What are 5 deepest oceans?

The press release stated that they planned to dive the Mariana Trench (Pacific Ocean, 11,033 m), Molloy Deep (Arctic Ocean, 5608 m), Puerto Rico Trench (Atlantic Ocean, 8605 m), South Sandwich Trench (Southern Ocean, 7235 m) and the Diamantina Trench (Indian Ocean, 8047 m).

Which ocean is coldest?

The Arctic Ocean | National Geographic Society.

What lives in Mariana Trench?

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.

Which ocean is the warmest?

The Indian Ocean has the warmest surface temperature of all the world¹s oceans, as most of it is found in the tropics.

What is the smallest ocean?

The Arctic Ocean is the smallest of the world's five ocean basins. A polar bear walks on the frozen surface of the Arctic Ocean. The freezing environment provides a home for a diverse range of creatures.

How deep has a human gone in the ocean?

Vescovo's trip to the Challenger Deep, at the southern end of the Pacific Ocean's Mariana Trench, back in May, was said to be the deepest manned sea dive ever recorded, at 10,927 meters (35,853 feet).

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'.

Which animal can dive the deepest?

Cuvier's beaked whales (Ziphius cavirostris) are master divers. These creatures hold the record for deepest plunge by a marine mammal. One whale dived to depths of nearly 3,000 meters (almost 1.9 miles). This species also holds the record for the longest dives.

How dark is the bottom of the ocean?

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. Animals that live in the abyssal zone feed on detritus raining down from above—or on each other.

What is the saltiest ocean?

Of the five ocean basins, the Atlantic Ocean is the saltiest. On average, there is a distinct decrease of salinity near the equator and at both poles, although for different reasons.

Who is the biggest ocean?

The Pacific Ocean is the largest and deepest of the world ocean basins. Covering approximately 63 million square miles and containing more than half of the free water on Earth, the Pacific is by far the largest of the world's ocean basins. All of the world's continents could fit into the Pacific basin.

Why is the ocean salty?

From precipitation to the land to the rivers to the sea

The rain physically erodes the rock and the acids chemically break down the rocks and carries salts and minerals along in a dissolved state as ions. The ions in the runoff are carried to the streams and rivers and then to the ocean.

Which ocean is the cleanest?

The South Pacific is the least polluted of the world's oceans. There are about 150 million metric tons of plastic in the oceans and a further 8 million metric tons are added to the oceans annually.

What is the safest ocean in the world?

Which ocean is in M shape?

Indian Ocean has 'M' Shape.

Which ocean has the most fish?

What is the youngest ocean?

The Indian Ocean is the smallest, geologically youngest, and physically most complex of the world's three major oceans (the others being the Pacific and Atlantic). Although it first opened some 140 million years ago, almost all of the Indian Ocean basin is less than 80 million years old.

How old is the ocean?

The ocean formed billions of years ago.

At this time, about 3.8 billion years ago, the water condensed into rain which filled the basins that we now know as our world ocean.

Why is it called the Dead Sea?

Despite its name, the Dead Sea is actually not a sea, but a hypersaline lake. Why is it called the Dead Sea? Because no life forms (plants or living creatures) could survive in its waters, although it does contain microbial life.

Where is the Dead Sea?

The Dead Sea, also called the Salt Sea, is a salt lake bordering Jordan to the east, and Israel to the west. Its surface and shores are 427 metres below sea level, Earth's lowest elevation on land.

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.

What is deep inside ocean?

The deep sea or deep layer is the lowest layer in the ocean, existing below the thermocline and above the seabed, at a depth of 1,000 fathoms (1,830 m) or more.
