What is the largest ocean on Earth?

The Pacific Ocean is the largest ocean on Earth, covering more surface area than all of the Earth's land combined. It spans over 63 million square miles and extends from the Arctic Ocean in the north to the Southern Ocean in the south, bordered by Asia and Australia to the west and the Americas to the east. This vast size means that it contains roughly half of the planet's oceanic water and plays a crucial role in global weather patterns, marine biodiversity, and international trade routes. Knowing that the Pacific Ocean is significantly larger than the Atlantic, Indian, and Arctic Oceans underscores its importance to Earth's geography and ecology. The Atlantic Ocean is the second largest, followed by the Indian Ocean, while the Arctic Ocean is the smallest.
