Which of the four oceans spans the longest longitude?

Among the four oceans, the Arctic Ocean has the longest longitude span.

Knowledge development in the Arctic Ocean;

Arctic Ocean [1], the name of the ocean (Arctic) comes from Greek, which means the ocean facing Ursa major. 1650, German geographer B. Varenius first divided it into an independent ocean called the Great Beiyang; 1845, which was named Arctic Ocean by the Geographical Society of London.

It was changed to the Arctic Ocean because it is at the northernmost part of the four oceans, and because the climate in this area is extremely cold and the surface of the ocean is covered with ice all the year round, so people call it the Arctic Ocean.

The Arctic Ocean is the smallest, shallowest and coldest ocean in the world. Roughly centered on the Arctic Circle, it is located at the northernmost part of the earth, surrounded by Eurasia and North America, and there is a narrow Bering Strait communicating with the Pacific Ocean. It is connected with the Atlantic Ocean through the Greenland Sea and many straits, and is the smallest ocean in the world.

The area is only 654.38+047.5 thousand square kilometers, less than 654.38+00% of the Pacific Ocean. Its depth is1097m, and its deepest point is 5527m. Ancient Greece once called it "the ocean facing Ursa major".

The area north of the Arctic Circle is called the Arctic Region or Arctic Region, which includes the northern parts of Asia, Europe and North America along the coast of the Arctic Ocean and many islands in the Arctic Ocean. The countries and regions around the Arctic Ocean are Russia, Norway, Iceland, Greenland (Denmark), Canada and the United States. There are dozens of different nationalities in the Arctic.

The Arctic Ocean is the surrounding area with the north pole as the center, and it is a vast water area. The Arctic Ocean, located in the Arctic Circle, has a total area of 1365438+ 10,000 square kilometers, which is the smallest of the four oceans in the world, only 1+04 in the Pacific Ocean. Therefore, the Arctic Ocean is also called the Arctic Ocean.

The total volume of seawater in the Arctic Ocean is 654.38+06.9 million cubic kilometers, the average depth is 654.38+0296 meters, and the Liedtke Trench is 5449 meters. The Arctic Ocean accounts for more than 60% of the Arctic area, and more than two-thirds of the sea surface is covered with huge ice cubes with a thickness of one and a half to four meters all the year round. Most of them are covered by sea ice all year round.

The sea ice in the central Arctic Ocean has existed for 3 million years and belongs to permanent sea ice. The average water depth of the Arctic Ocean is 1225m, which is 1/3 of that of the Pacific Ocean. The maximum water depth is 5527 meters, which is less than 1/2 of the Pacific Ocean. More than 2/3 of its area belongs to the underwater edge of the mainland, that is, there is a very broad continental shelf around the Arctic Ocean.
