Why is there only winter and summer in the Arctic?

The reason why the Arctic climate is particularly cold is that the earth's axis is tilted, and it is never possible to make orthophoto images. For the same reason, there are only two seasons in Xia Dong in the Arctic.

The Arctic Ocean is a huge frozen ocean, surrounded by many islands and coastal areas in North America and northern Asia. In winter, the sun is always below the horizon and the sea is completely frozen. In summer, the temperature rises above freezing point, the edge of the Arctic Ocean melts, and the sun hangs in the sky for several weeks.

The Arctic Ocean is rich in fish and plankton, which provides a rich food source for millions of seabirds nesting here in summer. At the same time, it is also food for seals, whales and other marine animals.

Extended data:

The important economic fish in the Arctic Ocean is cod. There are two kinds of cod: Atlantic cod and Pacific cod, which live in shallow water and feed on clams and other benthic animals. Barents Sea and Norwegian Sea are one of the largest fishing grounds in the world, catching a large number of cod, haddock, butterfly fish and hairy scale fish.

Arctic cod is a typical cold-water fish, which is distributed throughout the Arctic. When the temperature exceeds 5℃, they will disappear. It is a small and medium-sized fish, the longest of which can reach 36 cm, and it is one of the important economic fish in the Arctic.

In summer, Arctic cod mainly live on the edge of the frozen area of the Barents Sea in the Kara Sea. Juvenile Arctic cod feed on small phytoplankton and zooplankton. With the growth, the plankton it ate gradually changed from small to large, and some of them preyed on small fish.
