The five oceans from smallest to largest are: the Arctic, Southern, Indian, Atlantic and Pacific.
The Seven Seas include the Arctic, North Atlantic, South Atlantic, North Pacific, South Pacific, Indian, and Southern oceans. The exact origin of the phrase 'Seven Seas' is uncertain, although there are references in ancient literature that date back thousands of years.
Pacific, Atlantic, Indian, Arctic… and the Southern Ocean which is off the coast of Antarctica.
More modernly, the seven seas have been used to describe regions of the five oceans—the Arctic, North Atlantic, South Atlantic, North Pacific, South Pacific, Indian, and Southern Oceans.
Historically, there are four named oceans: the Atlantic, Pacific, Indian, and Arctic. However, most countries - including the United States - now recognize the Southern (Antarctic) as the fifth ocean. The Pacific, Atlantic, and Indian are the most commonly known.
It's time to update your maps, because the Earth now has a total of five oceans. Though accepted by scientists for some time, the Southern Ocean wouldn't be found on any National Geographic maps – until now. Cartographers at the National Geographic officially recognised the fifth ocean on World Ocean Day, 8 June 2021.
The Arctic 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. With an area of about 6.1 million square miles , the Arctic Ocean is about 1.5 times as big as the United States.
Soon after, the National Oceanic and Atmospheric Administration (NOAA) recognized the body of water as the fifth ocean in 1999 after the Board of Geographic Names approved the title, "Southern Ocean," reports Paulina Firozi for the Washington Post.
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.
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 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.
In terms of geography, seas are smaller than oceans and are usually located where the land and ocean meet. Typically, seas are partially enclosed by land. Seas are found on the margins of the ocean and are partially enclosed by land. Here, you can see that the Bering Sea is part of the Pacific Ocean.
Seas are generally much shallower than oceans, just as they are smaller. Regardless, some seas have great depths, such as the Caribbean, which is the deepest in the world at 7,686 meters—a number significantly higher than the average depth of the ocean.
Ocean salt primarily comes from rocks on land and openings in the seafloor. Salt in the ocean comes from two sources: runoff from the 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.
The Pacific 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.
The Arctic Ocean
The Arctic Ocean is the smallest, shallowest, and coldest part of the ocean.
The Indian Ocean
The Indian Ocean has the warmest surface temperature of all the world¹s oceans, as most of it is found in the tropics.
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. Near the equator, the tropics receive the most rain on a consistent basis.

The Dead Sea is fed mainly by the Jordan River, which enters the lake from the north. Several smaller streams also enter the sea, chiefly from the east. The lake has no outlet, and the heavy inflow of fresh water is carried off solely by evaporation, which is rapid in the hot desert climate.
The Dead Sea is a landlocked salt lake between Israel and Jordan in southwestern Asia.
