Oceanic divisions
| # | Ocean | Area (km2) |
|---|---|---|
| 1 | Pacific Ocean | 168,723,000 (46.6%) |
| 2 | Atlantic Ocean | 85,133,000 (23.5%) |

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.
What is the saltiest sea?
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 was the first ocean called?
Panthalassa
Pangea, also spelled Pangaea, in early geologic time, a supercontinent that incorporated almost all the landmasses on Earth. Pangea was surrounded by a global ocean called Panthalassa, and it was fully assembled by the Early Permian Epoch (some 299 million to about 273 million years ago).
What was the first ocean?
The Pacific Ocean is the oldest ocean in the world with the oldest part of it’s floor dating to around 180 million years. However, the Pacific Ocean is technically much older as it developed from the center of Panthalassa, an ancient ocean that first began forming around 750 million years ago.
Which is the youngest ocean?
The Indian Ocean is the smallest, geologically youngest, and physically most complex of the world’s three major oceans (the others being the Pacific and Atlantic). Although it first opened some 140 million years ago, almost all of the Indian Ocean basin is less than 80 million years old.
Why is ocean green?
As light bounces off and passes through water, it reflects the color blue back to our eyes, but microscopic algae and tiny sediments known as colored dissolved organic matter muddy the metaphorical waters and cause oceans to appear green, red, or brown.
