Because the Arctic is cold all year round, the Arctic is off-limits.
The Arctic region is the area near the North Pole within the Arctic Circle at 66°34 north latitude. The climate in the Arctic is cold all year round. Arctic Ocean.
It is a vast frozen ocean, surrounded by numerous islands and North America.
and the coastal areas of northern Asia. In winter, the sun is always on the horizon.
Below, the sea is completely frozen in ice.
In summer, temperatures rise above freezing, the marginal areas of the Arctic Ocean melt, and the sun hangs in the sky for weeks on end. The Arctic Ocean is rich in fish and plankton.
This provides abundant food for the millions of seabirds that nest here during the summer**.
At the same time, it is also seals, whales and other marine animals.
food. Most of the area around the Arctic Ocean is relatively flat and there are no trees growing. In winter, the ground freezes and the ground is covered with a thick layer of snow.
Environment:
Although most of the Arctic Ocean is covered in snow and ice, the water beneath the ice, like the rest of the world's oceans, flows in a constant pattern. If the tides are the pulse of the sea, then the circulation of the sea is the life of the sea.
The main role in the surface circulation of the Arctic Ocean is played by two currents: one is the Atlantic Ocean.
The West Spitsbergen Current, a tributary of the ocean current, is a warm current with high salinity from Greenland.
It enters the Arctic Ocean from the east and moves counterclockwise along the edge of the shelf.
The other is a transpolar current that comes in from the Chukchi Sea, flows past the North Pole and then out of the Greenland Sea, and flows into the Atlantic Ocean. Together, they control the basic characteristics of marine hydrology in the Arctic Ocean, such as the distribution of water masses and the exchange of water between the Arctic Ocean and the open sea.

Because the Arctic is uninhabited and an extremely cold region, it cannot be mined.

Because to protect the environment.
The increasing number of tourists visiting Antarctica will jeopardize the fragile environment of the region. Environmental protection is the number one priority for Antarctic tourism. The Antarctic ecosystem is so fragile that even a single alien seed can devastate Antarctica and threaten species patterns.
Developing safe and environmentally responsible Antarctic tourism has become a consensus for human development.
Antarctic tourism has been managed under the Antarctic Treaty framework and has been a key topic of the Antarctic Treaty Consultative Meeting. In addition, IAATO has developed and implemented environmental standards for the Antarctic tourism industry in accordance with the environmental requirements of the Antarctic Treaty system, and regularly provides reports on Antarctic tourism to the Antarctic Treaty Consultative Meeting.
At the beginning of the 19th century, the Antarctic continent was discovered. But because of the cold climate of Antarctica, there are no permanent inhabitants, and there are no immigrants from other places, so there are no settlers and no ** or state is established.
By the mid-20th century, the United Kingdom, France, Germany, Australia, New Zealand and other countries put forward territorial claims to the Antarctic continent, and since then the United States, Chile, Argentina and other countries have also put forward territorial claims to the Antarctic continent.
On December 1, 1959, representatives of 13 countries, including Argentina, Australia, Belgium, Chile, France, Japan, New Zealand, Norway, South Africa, the United Kingdom, the United States, and the Soviet Union, signed the Antarctic Treaty in Washington.
The treaty stipulates that Antarctica shall be used only for peaceful purposes, guarantees freedom of scientific exploration in the Antarctic region, promotes international cooperation in scientific exploration, prohibits all activities of a military nature and the nuclear and processing of radioactive materials in the Antarctic region, freezes claims to territorial ownership, and promotes international cooperation in science.

Harsh climates are more prone to hazards. The total area of the Antarctic continent is 13.9 million square kilometers, which is equivalent to the area of China and the Indo-Pakistani subcontinent combined, ranking fifth among all continents in the world. The entire Antarctic continent is covered by a huge ice sheet, with an average elevation of 2,350 meters, making it the highest continent in the world.
There are more than 220 kinds of minerals in Antarctica.
On February 9, 2020, a weather station on Seymour Island, Antarctica, recorded news of high temperatures.
Antarctica is divided into two parts: East Antarctica and West Antarctica. East Antarctica extends from 30°W to 170°E and includes Coates Land, Queen Maude Land, Enderby Land, Wilkes Land, George V Coast, Victoria Land, the Antarctic Plateau, and the Pole.
It covers an area of 10.18 million square kilometers. West Antarctica is located between 50°W and 160°W, including the Antarctic Peninsula, Alexandria Island, Ellsworth Land, and Bird Land, covering an area of 2.29 million square kilometers. Antarctica has only a few scientific expeditions and whaling teams from other continents.
The main factors that affect the wind on Earth are: horizontal pressure gradient, geostrophic deflection force, and frictional force. Among them, the horizontal pressure gradient is the key to the formation of the wind, which affects the strength of the wind, the geostrophic deflection force affects the direction of the wind, and the frictional force weakens the speed of the wind. >>>More
The Antarctic is colder and has more glaciers than the Arctic, because the Antarctic region is a continent with a weak ability to store heat, and the heat gained in the summer is quickly radiated, resulting in an average annual temperature of -56 in Antarctica. In the ocean around the Antarctic continent, a large amount of ice floats, forming huge icebergs. >>>More
Reasons: 1. Antarctica has a high latitude, a small solar altitude angle, a long atmospheric path through which solar radiation passes, more solar radiation weakened by the atmosphere, and less solar radiation reaching the ground. At the same time, due to the small solar altitude angle, the area of the same amount of solar radiation is large, and the solar radiation per unit area of the ground is less. >>>More
The saying that the Antarctic and the North Pole are half the day and the other year is night is not rigorous. But. There is also a certain truth in him. >>>More
Because the earth rotates left and right, not up and down, the north pole and north pole located above and below the earth are rarely exposed to sunlight. That's why it's cold.
