Which major ocean is the largest by surface area and total water volume, containing the deepest known oceanic trench, the Mariana Trench?

💡 Solution & Explanation

The Pacific Ocean is the largest and deepest of the Earth's oceanic divisions, spanning from the Arctic in the north to the Southern Ocean in the south, and housing the Challenger Deep in the Mariana Trench. The Atlantic Ocean is the second-largest ocean, shaped like an elongated 'S' separating the Americas from Europe and Africa. The Indian Ocean is bounded by Asia, Africa, and Australia, characterized by monsoon-driven seasonal current reversals. The Arctic Ocean is the smallest and shallowest of the five major oceanic divisions, located primarily in the polar north.
