Who named the ocean?

The word 1. Pacific first appeared in the 1920s of 16. It was originally named by the great navigator Magellan and his fleet. 1565438+On September 20th, 2009, Portuguese navigator Magellan led an expedition composed of 270 sailors to sail from Seville, Spain, and crossed the Atlantic Ocean to find new routes to India and China. The fleet of 65438+February 13 arrived in Rio de Janeiro Bay, Brazil for a short rest, then headed south and arrived at the port of San Julien on March 1520. Since then, the fleet has been fighting. Magellan struggled to suppress the Spanish fleet, launched a rebellion, and the fleet continued to go south. They braved the stormy waves and suffered a lot, reaching the southernmost tip of South America and entering a strait. This strait, which was later named after Magellan, was even more sinister, full of violent winds, huge waves and dangerous beaches and reefs. After 38 days of hard work, the fleet finally reached the western end of strait of magellan. However, at this time, there were only three ships left in the fleet, and half of the crew were lost.

After another three months of hard sailing, the fleet crossed Guam from South America and came to the Philippine Islands. There was no storm on this voyage, and the sea was very calm. The original fleet has entered the equatorial windless zone. The crew who experienced the previous waves said happily, "This is really the Pacific Ocean!" Since then, people have called this ocean between America, Asia and Oceania "Pacific Ocean".

The Pacific Ocean is the largest and deepest ocean in the world, with an original area of 108 and130,000 square kilometers. After the establishment of the Antarctic Ocean, the area was adjusted to155.57 million square kilometers, with an average depth of 4028 meters. The deepest part of Mariana Trench is11034m. From the north and south of the equator, it is divided into the North Pacific and the South Pacific. It extends from the west coast of the United States to the east coasts of Asia and Australia. It is also the ocean with the most earthquakes in islands, bays, trenches and volcanoes.

2. Atlantic Ocean: The word Daxi comes from the name of Atlas, the Hercules in ancient Greek mythology. It is said that Atlas lives in the Atlantic Ocean, can know the depth of any ocean, and has the power to stand firm. 1845, the Atlantic Ocean was named by the Geographical Society of London.

"Atlantic" is not a translated name, but an authentic domestic and foreign place name! Since the Ming Dynasty, China has always taken Leizhou Peninsula to Kalimantan as the boundary when expressing its geographical position, with the East China Sea to the east and the West Sea to the west. This is why we often call the Japanese easterners and the Europeans westerners. In Ming Shenzong, Matteo Ricci came to China to visit Emperor China. In China's way, he said he was an "Atlantic" man on the west side of "Little Western Ocean (as China said at that time)". It can be seen that at that time, we called the Atlantic Ocean "Atlantic Ocean", and there was no other translation of this name.

The English name of the ATLANTICOCEAN is Atlantic Ocean, which was called OCEAMUSATLANTICUS in ancient times. It is named after Atlas, the Hercules in ancient Greek mythology. Atlas can know the depth of any ocean and support pillars to separate heaven and earth. Legend has it that the Atlantic Ocean is where he lives. At first, the Greeks named the mountains in northwest Africa after the god Aras, and later they extended to the ocean outside Gibraltar. This name was quoted by the Dutch geographer Berthard Vasini (1622- 1650) in 1650.

The Chinese name "Atlantic" was first recorded in the Ming Dynasty. In the Ming Dynasty, it was customary to divide things from Leizhou Peninsula to kalimantan island, with "West" in the west and "East" in the east. So China used to call Europeans "Westerners" and Japanese "Orientals". At the end of Ming Dynasty, with the increase of geographical knowledge in Europe, the Indian Ocean was renamed "Little Western Ocean" and the sea west of Europe was called "Atlantic Ocean". After the introduction of western geography and maps, translators found it difficult to translate the word Atlantic into suitable Chinese, so they used to translate it into "ATLANTICOCEAN", which has been in use ever since.

The Indian Ocean lies between Asia, Africa, Oceania and Antarctica, and all its waters are in the Eastern Hemisphere. It is the third ocean in the world, and it is named Indian Ocean because it is located in the south of Indian Peninsula in Asia.

The Indian Ocean was called "Eritrea Sea" in ancient times, and it was first seen in the book History written by Herodotus (484- 425 BC) and his world map. The Greek word "ERYTHREA" means red, and its full name is Red Sea.

The name "Indian Ocean" appeared relatively late. Pombonius Mera, a Roman geographer in the late 1 century, was probably the first person to use this name. In the 10 century, this name was also used on the map of the world compiled by the Arab Ibn hucal. 15 15 officially used the Indian Ocean. At that time, the map compiled by Chenal, a cartographer from Central Europe, marked this ocean as "Indian Ocean in the East", and the word "East" here was relative to the Atlantic Ocean. 1497, Portuguese navigator Da Gama China Eastern Airlines searched for India, so he called the ocean he passed along the way the Indian Ocean. 1570, Ottley uz compiled an atlas of the world, removing the name of "Oriental Indian Ocean" and simplifying it to "Indian Ocean". This name is gradually accepted by people and becomes a common name.

4. How did the Arctic Ocean originate? Through long-term research, marine geologists believe that the formation of the Arctic Ocean is closely related to the rupture and disintegration of the Laoyagu land in the northern hemisphere. The process of submarine expansion began in the late Paleozoic and was mainly realized in the Cenozoic. It takes the earth's North Pole as the center, and produces the Arctic Ocean basin through the ocean floor expansion movement of the Eurasian plate and the North American plate. At present, the "Arctic Ridge" found at the bottom of the Arctic Ocean is the center line of the crust that produces the ice ocean floor. At the same time, two seamounts, the lomonosov Strait and the Mendeleev Strait, which are parallel to the mid-ocean ridge of the Arctic Ocean, have been found at the bottom of this ocean, indicating that the bottom of the Arctic Ocean has expanded more than once.
