What is the largest ocean that has ever existed on Earth?
When divided by continents, the Pacific Ocean will hold the title of the world’s largest ocean since the fall of Pangaea about 200 million years ago.
However, if current predictions of tectonic plate movement are correct, Australia will split the Pacific Ocean into two parts over the next 70 million years, According to scientists.
At the same time, the Atlantic Ocean will expand and take over the title of the largest ocean on Earth.
The largest ocean is now the Pacific Ocean, but another ocean covering up to 70% of the Earth’s surface existed 200 million years ago.
Earth’s largest ocean today, the Pacific Ocean, covers more than 30% of the planet’s surface, meaning about 165 million km2.
The widest point of this ocean is 19,000 kilometers, located between Colombia and the Malay Peninsula, according to UNESCO’s
Intergovernmental Oceanographic Commission (IOC UNESCO).
