The Pacific Ocean (also known as the withers sea) is the largest body of water on the face of the planet. It extends from the North Pole in the north to the Antarctic Ocean in the south, and is bordered by Asia and Australia in the west, and the Americas in the east.
It covers an area of 169.2 million km² (64.1 million sq mi). That is, it covers approximately 46% of the total area of the seas and 30% of the total area of the globe, i.e. one third. The equator divides it into the North Pacific Ocean and the South Pacific Ocean. The Mariana Trench in the northwest Pacific Ocean is the deepest point in the world, reaching a depth of 10,911 meters (35,797 feet). The Pacific Ocean was seen by Europeans in the early 16th century, and was first seen by Spanish explorer Vasco Nuñez de Balboa when he crossed the Isthmus of Panama in 1513 and named it after Mar del Sur, which is the South Sea. The current name was given by the Portuguese explorer Ferdinand Magellan during the Spanish expedition to circumnavigate the world in 1521, where he encountered the calm seas during the voyage and called it Mar Pacifico, meaning the calm sea.
The Pacific Ocean is equivalent to nearly a third of the Earth's surface, which is much larger than the entire land area, even if we add another African continent.
It extends approximately 15,500 kilometers (9,600 mi) from the Bering Sea in the Arctic to the northernmost part of the Arctic Circle in the Antarctic Ocean. ) from Indonesia to the coasts of Colombia and Peru—in the middle of the world, it's more than five times the diameter of the moon. The lowest known point on Earth is the Mariana Trench, which is 10,911 meters (35,797 feet) below sea level. Its average depth is 4,028 ~ 4,188 meters (14,000 ft). The Pacific Ocean contains approximately 25,000 islands (more than the total number of all the rest of the oceans combined), the majority of which are located south of the equator. Including partially submerged islands.
Currently the Pacific Ocean is shrinking due to plate tectonics, while the Atlantic Ocean is increasing in area, approximately one inch per year (2-3 cm/year) on 3 sides, averaging about 0.2 square miles (0.5 km²). ) annually.
Along the Pacific Ocean has irregular margins in the west spread in many seas, the largest of which are the Celebes Sea, Coral Sea, East China Sea, Philippine Sea, Japan Sea, South China Sea, Sulu Sea, Tasman Sea, and the Yellow Sea. The Pacific Ocean is joined by the Strait of Malacca and the Indian Ocean in the west, and the Drake Passage and the Strait of Magellan connect the Pacific Ocean with the Atlantic Ocean in the east. In the north, the Bering Strait connects the Pacific Ocean with the Arctic Ocean.
