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. The Southern Ocean is the ‘newest’ named ocean.
What are the 7 ocean of the world? 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.

On June 8, 2021, the National Geographic Society, which has been making maps since 1915, announced that from now on, there would be five oceans: the Atlantic, Pacific, Indian, Arctic, and Southern Ocean. Fittingly, the decision was revealed on World Oceans Day!

What are the 5 seas?
The five oceans from smallest to largest are: the Arctic, Southern, Indian, Atlantic and Pacific.
How many seas are on Earth? In general, a sea is defined as a portion of the ocean that is partly surrounded by land. Given that definition, there are about 50 seas around the world. But that number includes water bodies not always thought of as seas, such as the Gulf of Mexico and the Hudson Bay.
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. With an area of about 6.1 million square miles , the Arctic Ocean is about 1.5 times as big as the United States.
What is the deepest ocean?
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.
Where is the Black Sea? The Black Sea is located at the southeastern extremity of Europe. It is bordered by Ukraine to the north, Russia to the northeast, Georgia to the east, Turkey to the south, and Bulgaria and Romania to the west.
What is a sea vs ocean?
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.
Where is the Dead Sea? Where is the Dead Sea located? The Dead Sea is a landlocked salt lake between Israel and Jordan in southwestern Asia.
Why is the ocean salty?
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.
What is the 2nd largest ocean?
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.
What is the warmest ocean? The Indian Ocean has the warmest surface temperature of all the world¹s oceans, as most of it is found in the tropics.
Which ocean is the saltiest?
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.
What ocean is the shallowest?
Arctic Ocean. The Arctic Ocean is the smallest and shallowest of the world’s five major oceans. This water body is completely surrounded by the continents of Asia, North America, Europe and the island of Greenland.
Where is the White Sea? The White Sea is an inland sea in the north of the European part of Russia that belongs to the Arctic Ocean. The White Sea is covered with ice for six to seven months every year.
Why is the Dead Sea called the Dead Sea?
The sea is called « dead » because its high salinity prevents macroscopic aquatic organisms, such as fish and aquatic plants, from living in it, though minuscule quantities of bacteria and microbial fungi are present. In times of flood, the salt content of the Dead Sea can drop from its usual 35% to 30% or lower.
Where is the Yellow Sea? Lying between mainland China and the Korean peninsula, the Yellow Sea is one of the world’s largest areas of continental shelf covered in shallow water, providing for rich fishing grounds and an important site for migratory birds.
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.
Does the ocean end? While this question appears to have a simple answer, the reality is that all the world’s waterways are connected to each other. There are no borders within the water itself, rather the names were human constructs given to different oceans in regard to around which bodies of land they flow.
Which sea has no salt?
| Dead Sea | |
|---|---|
| Basin countries | Israel, Jordan, and Palestine |
| Max. length | 50 km (31 mi) (northern basin only) |
| Max. width | 15 km (9.3 mi) |
| Surface area | 605 km 2 (234 sq mi) (2016) |
Why Dead Sea is salty? In the arid low-lying desert, the water that collects in the Dead Sea evaporates more quickly than water in the open ocean, leaving vast quantities of salt behind, the MDSRC explains.
Why is it called Black Sea?
Why is the Black Sea black? The sea was first named by the ancient Greeks who called it « Inhospitable Sea. » The sea got this reputation because it was difficult to navigate, and hostile tribes inhabited its shores.

Can you drink ocean water? Drinking seawater can be deadly to humans.
Seawater contains salt. When humans drink seawater, their cells are thus taking in water and salt. While humans can safely ingest small amounts of salt, the salt content in seawater is much higher than what can be processed by the human body.
Is whale sperm in the ocean?
Ejaculate is three times as salty as seawater (although it made up of a somewhat different collection of ions). Therefore according to Snooki, one third of the ocean volume is whale sperm. Sperm is also less dense than seawater (due to the lipid content).
