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.
What 4 features make up the deep ocean basin?

What are 5 ocean basins?
The five ocean basins from largest to smallest are: the Pacific, Atlantic, Indian, Southern, and Arctic.
Which of the four ocean basins is the largest?
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.
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 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 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 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 the largest ocean basin?
the Pacific basin 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 Pacific is the oldest of the existing ocean basins.
What are the 7 ocean names?
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.

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.
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.
Are there 5 or 7 oceans?
There is only one global ocean. 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.
What are the 7 seas 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.

What is D colour of water?
The water is in fact not colorless; even pure water is not colorless, but has a slight blue tint to it, best seen when looking through a long column of water. The blueness in water is not caused by the scattering of light, which is responsible for the sky being blue.

Can the Dead Sea blind you?
Likewise, the intensely salty water would instantly burn and likely blind the eyes—both reasons why Dead Sea swimmers rarely fully submerge their bodies, Ionescu noted. "It's a very unique experience," Ionescu said of diving in the Dead Sea, but "I wouldn't recommend it for recreational diving."
Which sea can you not drown in?
The Dead Sea The Dead Sea is landlocked and in the lowest valley on earth. All the minerals of the surrounding countryside get washed into one pool, which in turn gets baked by the sun. This concentrates the salts so much so that the Dead Sea becomes times as salty as the ocean, which defines why people don't drown in the dead sea.
Is the Red Sea really red?
Normally, the Red Sea is an intense blue-green; occasionally, however, it is populated by extensive blooms of the algae Trichodesmium erythraeum, which, upon dying off, turn the sea a reddish brown colour.
