What is the information about the North Pole?

Arctic (English: northpole French: Arctique；; German: Arktis) refers to the northern end of the earth's rotation axis, that is, the point at 90 north latitude. The Arctic region refers to the area near the North Pole in the Arctic Circle at 66 34' north latitude. The climate in the Arctic is cold all year round. 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. Most areas around the Arctic Ocean are relatively flat, with no trees growing. In winter, the ground freezes and is covered with thick snow. In summer, snow melts, topsoil melts, and plants grow and bloom, providing food for animals such as reindeer and musk oxen. At the same time, carnivores such as wolves and polar bears also survive by preying on other animals. The Arctic is one of the most sparsely populated areas in the world. For thousands of years, Inuit (formerly Eskimos) have lived here for generations. Oil was discovered here, so many people came from the south to work here.

North Pole: refers to the northern end of the earth's rotation axis.

Arctic Circle: refers to the dividing line between the northern frigid zone and the northern temperate zone, and the latitude circle is 66 34' north latitude.

Arctic Ocean: The smallest, shallowest and coldest ocean in the world.

Arctic region: Arctic Ocean and its surrounding waters.

Scope: The Arctic refers to the vast area north of 66 34' north latitude (Arctic Circle), also known as the Arctic region. The arctic region includes the polar arctic ocean, marginal land coastal zones and islands, arctic tundra and the outermost coniferous forest belt. If the Arctic Circle is the boundary of the Arctic, the total area of the Arctic region is 2 1 10,000 square kilometers, of which the land part accounts for 8 million square kilometers. Some scientists, from the phenological point of view, take the average isotherm in July 10℃ (the ocean is at 5℃) as the southern boundary of the Arctic region. In this way, the total area of the Arctic region has expanded to 27 million square kilometers, of which the land area is about120,000 square kilometers. If the Arctic is defined by the distribution of plant species and all the Taiga forest belts are included in the Arctic, the area of the Arctic region will exceed 40 million square kilometers. What is the boundary of the Arctic region? The standards of countries around the Arctic are not uniform, but most people are used to taking the Arctic Circle as the boundary of the Arctic region from a geographical perspective. Figure 1 is the Arctic ice sheet map taken by NASA earlier, but by the end of 20 1 1, all the ice in the ocean had melted, and this trend will gradually spread to the ice sheet on the Arctic continent.
