What is the largest ocean in the world?

Why is the earth blue? This problem once troubled us. We always thought that blue was its original color, but later we learned that it was because there were many marine areas. Speaking of which. Do you want to know which is the largest ocean in the world? Next, I will answer your questions.

The Pacific Ocean is the largest ocean in the world, as follows.

The Pacific Ocean spans from the coast of the Antarctic continent to the Bering Strait, borders Asia and Oceania in the west, and borders America in the east, spanning 15 1? Latitude, the widest from north to south is 15500 km. Sea area 18 1344000 square kilometers, excluding sea area 16624 1000 square kilometers. Does the name of the Pacific Ocean come from Latin? Pacific Ocean? , meaning? A calm ocean? A Portuguese navigator employed by Spain? Magellan named. In June 5438 +0520 +654381October, Magellan led five ships to find a southwest exit (hereinafter referred to as strait of magellan) from the Atlantic Ocean and sailed west. After 38 days of stormy waves, he reached the calm sea, which he called the Pacific Ocean.

From the world map or globe, we can see that the world is blue, because the ocean area accounts for more than 70%, while the land area accounts for less than 30%. That vast ocean is divided into several oceans. Do you know which is the largest ocean in the world? The Pacific Ocean is the largest ocean in the world.

The Pacific Ocean is the largest ocean on the earth, accounting for about 46% of the earth's water surface and 32% of its total area. The span extends from the coast of the Antarctic continent to the Bering Strait, to Asia and Oceania in the west and to America in the east, with a span of 135? Latitude, the widest from north to south is 15500 km. Sea area 18 1344000 square kilometers, excluding sea area 16624 1000 square kilometers. Its average depth is about 4000m, the maximum depth is Mariana Trench (east of Mariana Islands), and the depth is 1 1, 033m. Most of the ocean surface is located near the equator and tropical latitudes.

The largest ocean in the world is the Pacific Ocean, which starts from Antarctica in the south, reaches the North Pole in the north, reaches Asia and Australia in the west and connects North and South America in the east. ? Pacific Ocean? The name comes from 15 19. The fleet led by Portuguese Magellan crossed the rough strait of magellan and then entered a new ocean. During the dozens of days' voyage to the Philippine Islands, the sea was calm and the weather was fine. The crew called the new ocean the Sea of Peace and translated it into the Pacific Ocean in Chinese.

The outline of the Pacific Ocean is approximately elliptical. The maximum length from north to south 15900 km and the maximum width from east to west 19900 km. It covers an area of 65,438+79 million square kilometers, accounting for 49.4% of the world's ocean area, which is more than 1/3 of the earth's surface area and larger than the total land area of the earth 1/5. The average depth of the Pacific Ocean (including marginal seas) is about 4,000 meters, which is more than 300 meters deeper than the average depth of the world's oceans. The total volume of seawater in the Pacific Ocean exceeds 700 million cubic kilometers, accounting for about 53% of the total ocean water in the world, making it the largest ocean.

There are many subordinate sea areas in the western Pacific Ocean, namely Bering Sea, Sea of Okhotsk, Sea of Japan, Yellow Sea, East China Sea and South China Sea from north to south. Heilongjiang, Yellow River, Yangtze River, Pearl River and Mekong River all flow into the Pacific Ocean through the sea. West longitude 150? The seabed in the east is milder than that in the west. Ridges over 600 meters underwater in the western Pacific Ocean form islands in some places. From the Aleutian Ridge in the Northwest Pacific to the Thousand Islands, Kogasawara, Mariana, Yapu and Palau; Extending eastward from Palau to Bismarck, Solomon and Santa Cruz; Finally, from Samoa to Tonga, Kemadek, Chatham and mcquarrie.

Because the land-sea ratio in the north is higher than that in the south, and the influence of Antarctic land ice sheet, the water temperature in the north Pacific is higher than that in the south Pacific. The salt content of seawater in windless area and variable wind area near the equator is lower than that in trade wind area. The cold water generated around the Antarctic continent has the greatest influence on the vertical flow in the Pacific Ocean.

Dense seawater around the polar regions sinks and then spreads northward, forming most of the bottom of the Pacific Ocean. Deep cold water flows northward to Japan from near Antarctica in the western Pacific Ocean with relatively obvious ocean currents. The tributary of the deep-sea mainstream flows eastward with cold water, and then flows to the polar regions of the two hemispheres. The deep-sea circulation is affected by the sinking of the surface water near the intersection of ocean currents, and it is at 35? To 40? The farther away from the equator, the deeper the sea sinks, and the most important convergence zone is at 55? To 60? amongst

islands

There are many Pacific islands, mainly distributed in the western and central waters, which are divided into mainland islands and islands according to their nature. Mainland islands are generally related to the mainland in geological structure, such as Japanese archipelago, Taiwan Province archipelago, Philippine archipelago, Indonesian archipelago and New Guinea, the second largest island in the world. Islands are divided into volcanic islands and coral islands. The vast sea area west of the central Pacific Ocean has three islands: Melanesia, Micronesia and Polynesia from west to east. Melanesian islands are mostly mainland islands, Hawaiian islands in Polynesia are famous volcanic islands, and Micronesia islands are almost all coral islands.

countries and regions

There are more than 30 independent countries in the Pacific region. There are Russia, China, South Korea, North Korea, Viet Nam, Cambodia, Laos and Japan on the west bank. On the east coast are Chile, Peru, Mexico, the United States, Canada and so on. There are Australia, New Zealand, Western Samoa, Nauru, Tonga and Fiji in the south. In addition, there are a dozen colonies belonging to the United States, Britain, France and other countries.
