All of the world's continents could fit into the Pacific basin.
Where are the major ocean basins?
The Pacific, Atlantic, and Indian Oceans are conventional ocean basins and are bounded by the continental masses or by ocean ridges and currents; they merge below 40° South latitude in the Antarctic Circumpolar current, or west Wind Drift, at the Southern (or Antarctic) Ocean.

Geographic features associated with deep-ocean basins include trenches, abyssal plains, ocean ridges and rises, and submarine mountainous regions.
What are the parts of ocean basin?
The basins of Earth's four ocean basins, the Atlantic, Pacific, Indian, and Arctic, differ from each other in many respects. Yet, they all contain certain common features such as oceanic ridges, trenches, and fracture zones and cracks, abyssal plains and hills, seamounts and guyots.
What ocean is number 4?
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.
Which ocean basin is the smallest?
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.

What is a basin in the ocean?
Ocean basins are the largest depressions on Earth. Edges of the continents, called continental shelves, form the sides of ocean basins. There are five major ocean basins, coordinating with the major oceans of the world: the Pacific basin, the Atlantic basin, the Indian basin, the Arctic basin, and the Southern basin.
What forms oceanic basins?
All ocean basins are formed from plate tectonic activity, weathering, and erosion. Seafloor spreading and subduction are the primary forms of plate tectonic activity that provide a pathway for molten rock to leave the earth's mantle and create a new oceanic crust.
What are the main features of ocean basins?
A number of major features of the basins depart from this average—for example, the mountainous ocean ridges, deep-sea trenches, and jagged, linear fracture zones. Other significant features of the ocean floor include aseismic ridges, abyssal hills, and seamounts and guyots.
What are the major physical features of ocean basins?

Which ocean is the deepest?
western Pacific Ocean 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. Challenger Deep is approximately 10,935 meters (35,876 feet) deep.
Why is the Indian Ocean called the Indian Ocean?
The Indian ocean is named after India because: India holds a central location which is at the head of the Indian Ocean. India in ancient times was an important location in the Indian Ocean which connected Europe with countries of Southeast Asia.
What are ocean basins 6?
There are two main divisions of the earth's surface. The large land masses are known as the continents and the huge water bodies are called the ocean basins. All the oceans of the world are connected with one another. The level of seawater remains the same everywhere.
What do all ocean basins have?
The basins of Earth's four ocean basins, the Atlantic, Pacific, Indian, and Arctic, differ from each other in many respects. Yet, they all contain certain common features such as oceanic ridges, trenches, and fracture zones and cracks, abyssal plains and hills, seamounts and guyots.
What is the 6th ocean?
The Southern Ocean is the 'newest' named ocean. It is recognized by the U.S. Board on Geographic Names as the body of water extending from the coast of Antarctica to the line of latitude at 60 degrees South. The boundaries of this ocean were proposed to the International Hydrographic Organization in 2000.
What is the 5th ocean?
Antarctic 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.
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. The Dead Sea is 306 m deep, the deepest hypersaline lake in the world.
Which ocean is hottest?
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 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. Near the equator, the tropics receive the most rain on a consistent basis.

How many ocean basins are there?
Even though there is one world ocean, it has traditionally been divided into four major ocean basins: the Arctic, the Atlantic, the Indian, and the Pacific.
Why are there ocean basins?
Over millions of years, ocean basins open and close, continents move and change shape, and mountains are pushed up and eroded away. Such dynamic processes continually reshape the surface of the Earth. The movement of rigid plates on the Earth's surface, known as plate tectonics, is the cause of these changes.
