Which ocean is the deepest?

The average depth of the ocean is about 3,688 meters (12,100 feet). The deepest part of the ocean 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 to 35,856 ft) by direct measurement from deep-diving submersibles, remotely operated underwater vehicles, and benthic landers and (sometimes) slightly more by sonar ...

and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench

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.

, which runs several hundred kilometers southwest of the U.S. territorial island of Guam.

Which is the deepest ocean in the world?

The Mariana Trench, in the Pacific Ocean, is the deepest location on Earth. According to the Exclusive Economic Zone (EEZ), the United States has jurisdiction over the trench and its resources.

What are the 5 deepest oceans?

The Five Deeps Expedition was the first to reach the deepest point in each of the Earth's five oceans: the Puerto Rico Trench in the Atlantic, South Sandwich Trench in the Southern Ocean, Java Trench in the Indian Ocean, Challenger Deep in the Pacific and Molloy Deep in the Arctic.

Which ocean is coldest?

The Arctic Ocean is the coldest ocean, with average temperatures of about 28°F, but with global warming the arctic is heating twice as fast as the rest of the world. This body of water is also the smallest of the world's oceans. Size: about 5,427,000 square miles. Depth: 3,406 feet on average.

Which ocean is deepest Atlantic or Pacific?

The Pacific Ocean is the largest and deepest ocean basin on Earth, covering more than 155 million square kilometers (60 million square miles) and averaging a depth of 4,000 meters (13,000 feet).

Which ocean is the warmest?

Looking at the entire oceans, however, the Pacific Ocean is by far the warmest overall ocean because it has about four times the intense sun-heated surface area in the tropics compared with the Atlantic Ocean.

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 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).

What lives in Mariana Trench?

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.

Are all oceans connected?

All the oceans are connected to each other. Water is always moving within and between the oceans in currents, tides, and waves. The oceans are so old that, over time, minerals have dissolved into the water that make it taste salty. Much of the salt in the oceans is made of the same stuff as ordinary table salt.

Is there deeper than Mariana Trench?

The deepest place in the Atlantic is in the Puerto Rico Trench, a place called Brownson Deep at 8,378m. The expedition also confirmed the second deepest location in the Pacific, behind the Challenger Deep in the Mariana Trench. This runner-up is the Horizon Deep in the Tonga Trench with a depth of 10,816m.

Why is the Mariana Trench so deep?

One reason the Mariana Trench is so deep, he added, is because the western Pacific is home to some of the oldest seafloor in the world—about 180 million years old. Seafloor is formed as lava at mid-ocean ridges. When it's fresh, lava is comparatively warm and buoyant, riding high on the underlying mantle.

How deep can fish underwater?

Study suggests fish brains swell too much to survive past a certain depth. Ocean-going fish can't live any deeper than 8200 meters, according to a new study. All fish have their limits—you'll never find sharks below 4 kilometers, for example—but why there aren't any fish at all below 8 kilometers remains a mystery.

Why is 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.

What is the real color of the sky?

As far as wavelengths go, Earth's sky really is a bluish violet. But because of our eyes we see it as pale blue.

Why is the ocean red?

Ocean water can appear red if there is a bloom of a specific kind of phytoplankton causing a discoloration of the sea surface. These events are called “Red tides.” However, not all red tides are harmful, and they are only considered harmful algal blooms if the type of plankton involved contains hazardous toxins.

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 ocean has the clearest water?

The Weddell Sea has been claimed by scientists to have the clearest waters of any ocean in the world.

Which is the largest ocean in the world?

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.

Which ocean is saltier Atlantic or Pacific?

As oceanographers have known for many years—but now can “see”—the Atlantic Ocean is saltier than the Pacific and Indian Oceans. Rivers such as the Amazon carry tremendous amounts of fresh runoff from land and spread plumes far into the sea.

Is Pacific or Atlantic bigger?

Covering approximately 20 percent of the Earth's surface, the Atlantic Ocean is the second largest ocean basin in the world, following only the Pacific. However, it is only slightly larger than half the size of the Pacific Ocean.

How deep is the Black Sea?

Black Sea, Sea between Europe and Asia. Bordered by Ukraine, Russia, Georgia, Turkey, Bulgaria, and Romania, it has a maximum depth of 7,250 ft (2,210 m). The Black Sea proper has an area of 163,000 sq mi (422,000 sq km).
