1. The largest ocean in the world: the Pacific Ocean (about 181.344 million square kilometers, accounting for about 1/2 of the global ocean area)

The Pacific Ocean is the largest and deepest ocean with the most marginal seas and islands in the world. It lies between Asia, Oceania, Antarctica and North and South America. The longest from north to south is about 15,9 kilometers, and the widest from east to west is about 19, kilometers, with a total area of 181.344 million square kilometers, an average depth of 3,957 meters and a maximum depth of 11,34 meters.

2. The smallest ocean in the world: the Arctic Ocean (about 13 million square kilometers)

The Arctic Ocean, also known as the Arctic Sea, 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 has a narrow Bering Strait communicating with the Pacific Ocean. It is connected with the Atlantic Ocean through the Greenland Sea and many straits.

The Arctic Ocean is the smallest ocean in the world, with an area of only 14.75 million square kilometers, less than 1% of the Pacific Ocean. Its depth is 197 meters and the deepest is 5527 meters. Ancient Greece once called it "the ocean facing Ursa major".

In p>1845, it was named by the Geographical Society of London, England, and translated into the Arctic Ocean by Chinese. The foreign name Arctic comes from Greek, which means the ocean facing Ursa major. ) On August 25th, 212, the sea ice area in the Arctic Ocean was the smallest in the history of observation.

3. The deepest ocean in the world: the Pacific Ocean (the deepest depth is 11,34 meters)

The Pacific Ocean, which reaches the Bering Strait in the north, 65 44' north latitude, and reaches Antarctica in the south, 85 33' south latitude and spans 151 latitude. East to 78 8' west longitude, west to 99 1' east longitude, spanning 177 longitudes. The length from north to south is about 15,9 kilometers, and the maximum width from east to west is about 19,9 kilometers.

From the coast of Colombia in South America to the Malay Peninsula in Asia, the longest thing is 21,3 kilometers. Including the sea is 714.41 million cubic kilometers, excluding the sea is 696.189 million cubic kilometers.

The average depth including the genus sea is 3939.5 meters, and the average depth excluding the genus sea is 4187.8 meters, and the known maximum depth is 1133 meters, which is located in the Mariana Trench.

The Bering Strait, which is only 12km wide in the north, communicates with the Atlantic Ocean in the southeast via the Drake Strait between Tierra del Fuego in South America and Graham Land in Antarctica. The boundary between the southwest and the Indian Ocean is: from Sumatra Island to Timor Island via Java Island, then to Cape London in Australia via Timor Sea, then from southern Australia via bass strait, and from Tasmania to the Antarctic continent.

4. The world's ocean with the widest latitude: Atlantic Ocean

The Atlantic Ocean is the second ocean in the world, accounting for nearly 2% of the earth's surface area, with an original area of 91.655 million square kilometers. After the establishment of the antarctic ocean, the area was adjusted to 76.762 million square kilometers, with an average depth of 3,627 meters, and the deepest Puerto Rican trench reached 9,219 meters. The Atlantic Ocean is "S" shaped and divided into the North Atlantic and the South Atlantic by the equator.

In addition, there are several subsidiary seas in the Atlantic Ocean, such as the Mediterranean Sea, the Caribbean Sea, the North Sea, the Baltic Sea and the Gulf of Mexico. The Atlantic Ocean is far away from the north and south, so the climate is diverse, from the polar climate of Greenland in the north to the tropical desert or rainforest climate along the coast of West Africa and Brazil. However, in Europe, the United States, Canada, and the waters south of Brazil and the Gulf of Guinea, there are heavy winds and waves all the year round.

5. The ocean with the widest longitude in the world: the Arctic Ocean

is roughly centered at the north pole, between Asia, Europe and North America, and is surrounded by three continents. The Arctic Ocean spans 36 longitude, which is the longest ocean in the world.

6. The ocean with the highest latitude in the world: the Arctic Ocean

The shelf of the Arctic Ocean is developed, with a maximum width of over 1,2 kilometers. The peak is generally 1-2m away from the water surface, and some peaks are only over 9m away from the water surface, with intense volcanic and seismic activities. It divides the Arctic Sea into Canada Basin, makarov Basin (Mendeleev Ridge divides this basin into Canada and makarov) and Nansen Basin.

The depths of the basins are all between 4, and 5, meters. There are many mounds and depressions in the middle of the Arctic Ocean. There is an east-west submarine highland between Greenland and Svalbard, which is the boundary between the Arctic sea area and the Nordic sea area. The northeastern part of the Nordic Sea is the continental shelf, the southwestern part is the deep water area, and the Greenland Sea is the deepest, reaching more than 5,5 meters.
