Early life

The Pacific Ocean is the largest of the Earth's oceanic divisions. Its name is derived from the Latin name Mare Pacificum, "peaceful sea", bestowed upon it by the Portuguese explorer Ferdinand Magellan. It extends from the Arctic in the north to Antarctica in the south, bounded by Asia and Australia in the west, and the Americas in the east. At 169.2 million square kilometres (65.3 million square miles) in area, this largest division of the World Ocean – and, in turn, the hydrosphere – covers about 46% of the Earth's water surface and about 32% of its total surface area, making it larger than all of the Earth's land area combined.[1] The equator subdivides it into the North Pacific Ocean and South Pacific Ocean. The Mariana Trench in the western North Pacific is the deepest point in the Pacific and in the world, reaching a depth of 10,911 metres (35,798 ft).[2]

The Strait of Magellan (often referred to as the Straits of Magellan and rarely as the Magellanic Strait) comprises a navigable sea route immediately south of mainland Chile and north of Isla Grande de Tierra del Fuego. The waterway is the most important natural passage between the Pacific and the Atlantic oceans, but it is considered a difficult route to navigate because of the inhospitable climate and the narrowness of the passage.
