Analysis: One, the Pacific Ocean.

Area: It is about 15,900 kilometers long from north to south, about 19,900 kilometers wide from east to west, and 179.68 million square kilometers of field difference. It accounts for 35% of the total area of the world's oceans.

The Pacific Ocean is the largest, deepest, and most island-dense of the four oceans on Earth.

There are about 10,000 islands in the Pacific Ocean, with a total area of more than 4.4 million square kilometers, accounting for about 45 of the world's total island area. The mainland islands are mainly distributed in the west, such as the Japanese archipelago, Kalimantan, New Guinea, etc.; There are many scattered ocean islands (volcanic islands, coral islands) in the central part of the country. The topography of the seabed can be divided into three parts: the central deep water area, the marginal shallow water area and the continental shelf.

Abyssal basins below roughly 2,000 m account for about 87 of the total area, marginal sections between 200 and 2,000 m and continental shelves up to 200 m approximate. There is a large ocean basin in the northern half, and there are many islands in the west, and there are deep trenches on the outer side of the island arc. The northern and western marginal seas have wide continental shelves, and the deep waters in the central part are more than 5,000 metres deep.

The Hawaiian Islands and the Lane Islands divide the central deepwater zone into the Northeast Pacific Basin, the Southwest Pacific Basin, the Northwest Pacific Basin, and the Central Pacific Basin. There are a large number of volcanic cones on the ocean floor. The shallow marginal waters are mostly more than 5,000 metres deep, and the basin area is small.

II. Atlantic.

Area: It covers an area of 90,000 square kilometers, accounting for about half of the ocean area, about half the area of the Pacific Ocean, and is the second largest ocean in the world.

Important islands and archipelagos: The islands of Great Britain, Ireland, Iceland, Newfoundland, Cuba, Hispaniola and many islands in the Caribbean and Mediterranean, with a small portion of Greenland also located in the Atlantic Ocean.

Third, the Indian Ocean.

Area: 70,000 square kilometers. It accounts for about the total area of the world's oceans, and is the third largest ocean in the world.

Islands: There are many islands in the Indian Ocean, most of which are mainland islands, such as Madagascar and many small islands on the eastern edge of Africa, as well as Socotra, Sri Lanka, Andaman Islands, Nicobar Islands, Mintawe Islands, etc. There are also many volcanic islands such as Reunion, Comoros, Amsterdam, Croze, Kerguelen, etc.

In addition, the Lakshadweep Islands, Maldives Islands, and Chagos Islands in the northern part of the Central Indian Ocean Ridge, as well as Christmas Island and the Kosong Pre-Picos Islands in southwest Java are all coral islands.

Fourth, the Arctic Ocean.

Area: 13.1 million square kilometres, about 1,14 the size of the Pacific Ocean. It occupies about the total area of the world's oceans and is the smallest and shallowest of the four oceans on Earth.

Islands: northern Canada, Iceland, Greenland (Denmark).

There are 13 countries and regions in total. It has a population of 100 million, accounting for about the world's total population, ranking fifth in the world.

Antarctica: With an area of 14 million square kilometers, it accounts for about the world's total land area and is the fifth largest continent in the world. Antarctica has only a few scientific expeditions and whaling teams from other continents, and no settled inhabitants.

Europe: With an area of about 10 million square kilometers, it accounts for about the total land area of the world, only larger than Oceania, and is the sixth largest continent in the world. There are 37 countries and regions in total. With a population of 100 million, accounting for about the world's total population, it ranks second in the world and is the continent with the largest population density.

Oceania: With an area of about 9 million square kilometers, about 6% of the world's total land area, Oceania is the smallest continent in the world. There are 24 countries and regions in total. With a population of 27 million, it is the least populous continent in the world except for Antarctica.

The smallest of the world's four oceans is the Arctic Ocean, which has a total area of 10,000 square kilometers and is the smallest. It is nearly 2 million square kilometers smaller than Antarctica's 14 million square kilometers. The Arctic Ocean is about 4,233 kilometers wide at its widest point and 1,900 kilometers at its narrowest point.

The Arctic Ocean is located in the Arctic and is frozen all year round. It was officially named the Arctic Ocean at the Geographical Society of London in 1845.

The Arctic Ocean is the smallest ocean in the world, between Asia, Europe, the North American continent and Greenland. Approximately the world's oceanic area, the volume of sea water is 10,000 cubic kilometers, the average depth is 1,225 meters, and the maximum depth is 5,527 meters (located in the northeastern part of the Greenland Sea).

The Arctic Ocean is covered in snow and ice almost for most of the year, and its average temperature rarely rises above freezing, however, the ocean is by no means barren.

In the seawater, known as saltwater channels, there are bacteria and algae in the tunnels, which provide food for flatworms and other creatures that have tunnels, melting on top of the ice to form ponds that form biomes.
