The World Ocean, world ocean, or global ocean, is the interconnected system of the Earth's oceanic (or marine) waters, and comprises the bulk of the hydrosphere, covering almost 71% of the Earth's surface, with a total volume of 1.332 billion cubic kilometres.[1]
The unity and continuity of the World Ocean, with relatively free interchange among its parts, is of fundamental importance to oceanography.[2] It is divided into a number of principal oceanic areas that are delimited by the continents and various oceanographic features: these divisions are the Atlantic Ocean, Arctic Ocean (rarely considered a sea of the Atlantic), Indian Ocean, Pacific Ocean, and Southern Ocean (typically reckoned instead as just the southern portions of the Atlantic, Indian, and Pacific Oceans). In turn, oceanic waters are interspersed by many smaller seas, gulfs, and bays.
A global ocean has existed in one form or another on Earth for eons, and the notion dates back to classical antiquity (in the form of Oceanus). The contemporary concept of the World Ocean was coined by the Russian oceanographer Yuly Shokalsky in the early 20th century to describe what is basically a solitary, continuous ocean that covers and encircles most of the Earth.
While continuous, the World Ocean can be visualized as being centered on the Southern Ocean. The Atlantic, Indian, and Pacific Oceans can be seen as bays or lobes extending northward from the Southern Ocean. Farther north, the Atlantic opens into the Arctic Ocean, which is connected to the Pacific by the Bering Strait:
The approximate shape of the World Ocean can for most purposes be treated as constant, although in fact it is not: continental drift continually changes its structure

The pacific is by far the largest ocean, the Atlantic is next & then the Indian ocean.
The Arctic Ocean covers about 3% of the Earth's surface.
Approximately, 72.1% of the Earth's surface is covered by Ocean.
The Indian Ocean
The ocean covers up 71% of the earth. 97% of the earth is water.
Yes, the oceans cover approximately 70% of the earth's surface.
The oceans cover an area of 71% of the Earth's surface.
The four oceans are the Pacific Ocean, Atlantic Ocean, Indian Ocean, and Arctic Ocean. They cover a significant portion of the Earth's surface and are interconnected, playing a crucial role in regulating the planet's climate and ecosystems.

Earth's oceans cover about 70% of the planet's surface.
The Pacific Ocean covers about 28% of the global surface. It is larger than the total land area of the world.
it covers up about 68.47 million % of the earths surface
