The Pacific Ocean is the largest and deepest of the Earth’s oceanic divisions, covering an area of 165.2 million km2 (63.8 million sq mi).
To get an inkling of how vast this body of water is, it’s larger than Earth’s entire combined landmass and comprises 32% of Earth’s total surface area. Plus, only about 2.5% of the water on Earth is fresh water – the other 97.5% is saline.
