The Pacific Ocean or Ocean of Shades (from Spanish: Pacifico, meaning calm) is the largest body of water in the world, and covers approximately one third of the Earth's surface, with a surface area of ​​165,250,000 km² (63.8 million sq mi2) . It extends about 15,500 km (9,600 mi) from the Bering Sea in the Arctic to the ice cap of the Ross Sea in Antarctica in the south. The Pacific Ocean reaches its greatest east-west width at about 5 degrees N latitude, where it extends about 19,800 km (12,300 mi) from Indonesia to the coast of Colombia. The western boundary of this ocean is usually placed in the Malacca Strait. The lowest point on Earth's surface, the Mariana Trench, is also in the Pacific Ocean. This ocean is located between Asia and Australia to the west, America to the east, Antarctica to the south and the Arctic Ocean to the north. The Pacific Ocean consists of about 25,000 islands (more than the number of islands in the world's oceans combined), the majority of which are south of the equator. (See: Pacific Islands.) On the irregular boundary of the Pacific Ocean are many oceans, the largest of which are the Celebes Sea, Coral Sea, East China Sea, Sea of ​​Japan, South China Sea, Sulu Sea, Tasman Sea and Yellow Sea. The Strait of Malacca connects the Pacific Ocean with the Indian Ocean in the west, and the Strait of Magellan connects the Pacific Ocean with the Atlantic Ocean in the east. The Portuguese explorer Fernando de Magelhaens is the person who named the Pacific Ocean. For most of his journey from the Strait of Magellan to the Philippines, Magellan did feel the serenity of the ocean. However, the Pacific Ocean is not always calm. Where the Atlantic Ocean is widening, the Pacific Ocean is shrinking. This causes many earthquakes. Many hurricanes and hurricanes destroy islands in the Pacific and the land around the Pacific is filled with volcanoes and is frequently shaken by earthquakes. The tsunami, caused by an earthquake on the seabed, has destroyed many islands and collapsed city buildings. The Pacific Ocean itself is divided into two, namely the North Pacific Ocean and the South Pacific Ocean. The Pacific Ocean is divided into two because of its enormous breadth.

Geological history of its formation

In geological history, it is stated that the beginning of the Pacific Ocean came from the Panthalassa Superocean at the end of the Precambrian. When the Supercontinent Pannotia split apart about 540 million years ago, the Panthalassa Ocean began to expand and take up the entirety of the Pan-African and Mirovoi Oceans which were its predecessors. Panthalassa continued to expand until the formation of Pangea and eventually, it became a Superocean and took almost 70% of the Earth's surface during the Mesozoic. At the beginning of the Jurassic period, Pangea began to fragment, eventually Panthalassa began to shrink and the Pacific oceanic plate began to form about 200 million years ago, through the movement of tectonic plates from mantle convection, and contains the youngest lithosphere that can directly delimit Earth's geodynamic history around Pangea. The split formed two continents, Laurasia and Gondwana, about 140 million years ago the Atlantic Ocean was formed, and the continents began to split. In the Cenozoic era, Panthalassa finally disbanded and the remnants of its Ocean can still be found in all corners of the World Ocean. Meanwhile, the largest part of Panthalassa today, the Pacific Ocean only takes more than 40% of the SuperOcean, which means Panthalassa is very large. Because the Pacific Ocean originated from Panthalassa, Panthalassa is sometimes also called the Paleo-Pacific or Proto-Pacific Ocean.
