The Pacific Ocean is the biggest water (ocean) in the world. It covers more than one-third of the Earth's surface and nearly half of Earth's water surface.
Here's a bit more context:
- The Pacific Ocean is vast, stretching from the Arctic in the north to the Southern Ocean in the south.
- It contains approximately half of all the free water on Earth.
- It's significantly larger than the Atlantic, Indian, Southern, and Arctic Oceans.
In short, when we refer to the "biggest water," the Pacific Ocean is what we're talking about.
