[China - Xinjiang]

Xinjiang Uygur Autonomous Region, with an area of ​​approximately 1.66 million square kilometers, ranks first in my country.

The overall terrain pattern of Xinjiang is "three mountains sandwiched by two basins", from north to south: Altai Mountains, Jungar Basin, Tianshan Mountains, Tarim Basin, and Kunlun Mountains.

The Tarim Basin, with an area of ​​approximately 560,000 square kilometers, is the first of the four major basins in my country and the largest inland basin in the world.

The Jungar Basin, covering an area of ​​approximately 380,000 square kilometers, is the second largest basin in my country.

The Taklimakan Desert is the largest desert in my country and ranks tenth in the world. It is about 1,000 kilometers long from east to west and about 400 kilometers wide from north to south, covering an area of ​​about 340,000 square kilometers.

Gurbantunggut Desert, covering an area of ​​approximately 50,000 square kilometers, is the second largest desert in my country.

The main source of the Tarim River is the Yarkand River, which originates from the southeastern foot of Telimukan Peak in the Karakoram Mountains and flows into Lop Nur along the northern edge of the Taklimakan Desert. With a total length of 2,327 kilometers, it is the longest inland river in China.

Hami Basin, Turpan Basin, collectively known as Turpan-Hami Basin, covers an area of ​​approximately 53,500 square kilometers. Aydin Lake in the middle of the Turpan Basin has an altitude of -154 meters, making it the lowest depression in China.

[USA - Alaska]

The United States covers an area of ​​approximately 9.37 million square kilometers. The mainland is 4,500 kilometers long from east to west and 2,700 kilometers wide from north to south. The United States has a population of approximately 333 million (February 2021), of which non-Hispanic whites account for approximately 62.1%, Hispanics account for approximately 16.9%, and African Americans account for approximately 13.4%.

Alaska is located at the northwest tip of the North American continent, bordering Canada to the east and surrounded on three sides by the Arctic Ocean, the Bering Sea and the North Pacific Ocean.

Alaska covers an area of ​​approximately 1.7179 million square kilometers, which is close to 20% of the area of ​​the United States. It is the largest state in the United States and is tens of thousands of square kilometers larger than Xinjiang in my country.

Alaska has Brooks Ridge in the north, the Alaska Range in the south, and the Yukon River and Valley in the middle. It has 17 of the top 20 highest mountains in the United States. The highest peak, Mount Denali, is about 6,194 meters above sea level and is the highest peak in North America.

Alaska has a cold climate, a vast territory and sparsely populated areas. Its total population is about 740,000 (2020), ranking 48th among the 50 states in the United States.

The most northwest corner of the North American continent and the northeastern corner of the Asian continent, the shortest distance is about 83 kilometers. But in the middle of the Bering Strait, there are two islands, one large and one small, called the Diomede Islands, which belong to Russia and the United States. The big island in the west is called Ratmanov Island, a typical Russian name, and the small island in the east is called Little Diomede Island, which belongs to the United States. Russia's Ratmano Island and America's Little Diomede Island are only 4 kilometers apart.

In 1867, the United States spent $7.2 million to purchase Alaska from Russia. Now there is a very interesting topic: whether Russia regrets selling Alaska and whether it is possible to buy Alaska back. Russia certainly has regrets, but it is impossible to buy back Alaska.

[Russia - Sakha Republic]

Russia has an area of ​​about 17.0982 million square kilometers, ranking first in the world. It is about 9,000 kilometers long from east to west and about 4,000 kilometers wide from north to south. Russia has a population of 146 million, ranking only ninth in the world. It is not only vast and sparsely populated, but also has many boys and girls. The male to female ratio has remained at around 46.2%: 53.8% for a long time.

The Sakha Republic is about 2,000 kilometers wide from east to west, about 2,500 kilometers long from north to south, and covers an area of ​​about 3.0835 million square kilometers. It is the largest republic in Russia and the largest first-level administrative region in the world.

If the Sakha Republic was a country, its area would rank seventh in the world after Russia, Canada, China, the United States, Brazil, and Australia, just slightly larger than India.

The Sakha Republic is close to the Arctic Ocean, and 40% of its land is located within the Arctic Circle. It has winter for seven months a year, and the lowest temperature is about -70°C. Due to the cold climate, the Sakha Republic is vast and sparsely populated, with a population of only about 960,000 (2018).

The mountains and plateaus of the Sakha Republic account for about 2/3 of the total area. There are the Central Siberian Plateau in the west and the Verkhovyansk Mountains and Chersky Mountains in the east. The highest point is Pobeda Mountain in the Chersky Mountains, with an altitude of about 3147 meters.

The main trunk of the Lena River enters the Sakha Republic from the southwest, draws a semicircle, flows northward, and finally flows into the Laptev Sea of ​​the Arctic Ocean.
