Wandering earth has little knowledge of geography.

The sun is about to be destroyed. In the past countless years, the sun, as the pillar of human spirit, has become a symbol of death and terror.

Humans choose to fight to the end, not to die. The huge earth escape plan began to be implemented.

And the man-made environment of ordinary size that human beings can create can't stand long-distance escape. Therefore, human beings have to install a huge earth engine on one side of the earth, turning the whole huge earth environment into a new immigration ark, thus escaping from the solar system and heading for a new home.

Price is high. Art, ethics, common sense, and once familiar features have disappeared from human nature, and many lost lives are like stars. All that's left is a strong desire to survive.

Doubt and suspicion once triggered the fire of human rebellion, but the final disappearance of the sun instantly calmed everything down, and human beings finally embarked on a long journey of wandering with hope. "Earth, my wandering earth" has become the last words of countless people born in this era.

It contains the eternal desire of mankind-we want to live.

Step 2: geographical tips

1。 "East China" generally refers to six provinces and one city in East China, including Shandong, Jiangsu, Zhejiang, Fujian, Anhui, Jiangxi and Shanghai.

2。 Qinghai-Tibet Plateau is the largest plateau in China and the highest average altitude in the world. Its land area is 2.4 million square kilometers, with an average elevation of 4,000? 5000 meters, known as the "roof of the world" and "roof of the world".

3。 The Antarctic continent has an extremely low climate all year round and is covered with ice and snow, which belongs to the polar climate.

4。 The Himalayas, including many of the highest mountains in the world, have more than 1 10 peaks with an altitude of 7300 meters (24000 feet) or more. One of them is Mount Qomolangma (also known as Mount Qomolangma and Sagama Tower), which is 8844.43 meters (290 17. 16 feet) high. The majestic peaks of these mountains stand above the permanent snow line.

5。 Tropical rainforest climate, also known as "equatorial rainy climate". It is distributed on both sides of the equator 10 latitude. It is hot and rainy all year round, with an average monthly temperature of 25 ~ 28℃ and an annual precipitation of over 2000 mm, with even seasonal distribution and no dry season. It mainly appears in Amazon Plain in South America, Congo Basin and Gulf of Guinea in Africa, most parts of Malay Archipelago in Asia and southern Malay Peninsula.

6。 Provinces where the Yangtze River and the Yellow River flow: (1) Yangtze River: Qinghai, Sichuan, Yunnan, Chongqing, Hubei, Hunan, Jiangxi, Anhui, Jiangsu, Zhejiang, Shanghai 1 1 provinces and cities. (2) Yellow River: It flows through 9 provinces and regions including Qinghai, Sichuan, Gansu, Ningxia, Inner Mongolia, Shanxi, Shaanxi, Henan and Shandong.

7。 Climatic zones across North America (from north to south): North Cold Zone, North Temperate Zone and Tropical Zone.

8。 The water body of the earth, in which seawater accounts for 97.3% and fresh water only accounts for 2.7%. Iceberg and ice cap water account for 77.2% of fresh water resources, groundwater and soil water account for 22.4%, lake and swamp water accounts for 0.35%, river water accounts for 0. 1%, and atmospheric water accounts for 0.04%.

9。 Snow is a natural phenomenon that water or ice condenses in the air and falls, or refers to falling snowflakes. Snow is the solid form of water. Snow only occurs under the influence of extremely cold temperatures and extratropical cyclones, so there are fewer opportunities for snow in subtropical and tropical areas.

10。 Frost is the condensation of water vapor (that is, gaseous water) when the temperature is very low, much like snow. On cold winter mornings, outdoor plants usually frost. This is because plants dissipate heat slowly at night, the ground temperature is particularly low, and the water vapor is not emitted quickly. When it gathers on the surface of plants, it freezes and forms frost. Scientifically speaking, frost is made up of ice crystals, similar to dew. When the relative humidity in the air reaches 100%, water is separated from the air. The only difference between the two is that the dew point (the temperature at which water vapor liquefies into dew) is higher than the freezing point, while the frost point (the temperature at which water vapor condenses into frost) is lower than the freezing point, so frost will only appear when the temperature near the surface is below zero degrees Celsius.

1 1。 If snow melts, it must absorb the heat around it. When the heat in the air is absorbed by snow, people will feel cold. On a snowy day without the sun, if it is cold, it is because the temperature is low! So people feel that it is colder when melting snow than when it snows.

12。 When launching a satellite, the closer to the equator, the better, because the closer to the equator, the greater the centrifugal force of the earth, which can save rocket fuel.

13。 In summer, influenced by warm front rain, the Yangtze River basin is rich in precipitation, reaching the maximum value in a year. The Yangtze River has a large runoff, so it dilutes the seawater in the Yangtze River estuary, and makes the salinity of the surface seawater in the Yangtze River estuary reach the minimum value in a year.

14。 The lowest inland basin in China is located in the eastern part of Xinjiang, which is an intermountain fault basin on the southern slope of the East Tianshan Mountains. There are Bogda Mountain in the north and Kuruk Mountain in the south, covering an area of about 50,000 square kilometers. The central part of the basin is about 4000 square kilometers above sea level, and the water surface of Aiding Lake is-1.54 meters (meters).

15。 Zengmu shoal, located at the southern tip of Nansha Islands (3 58 ′ north latitude and11217 ′ east longitude), is the southernmost tip of China territory. About 52 nautical miles southwest of Chengping Reef. According to the investigation of Experiment No.3 Ship 1985- 1986 of South China Sea Institute of Oceanography, the shallowest water depth is17.5m, which is spindle-shaped, and the reef ridge is an underwater coral reef with an area of 2. 12 square kilometers. Zengmu shoal is not occupied by any country, and our naval fleet will cruise Zengmu shoal irregularly.

3. A little common sense of geography is urgent and simple

General knowledge of geography in China: topography

4. What did the Wandering Earth talk about?

The Wandering Earth is adapted from Liu's novel of the same name. Set in 2075, the film tells the story that the sun is about to be destroyed and is no longer suitable for human survival. In the face of desperation, mankind will launch the "Wandering Earth" plan, trying to escape from the solar system with the earth and find a new home for mankind.

Synopsis: In recent years, scientists have found that the sun is rapidly aging and expanding, and the whole solar system, including the earth, will be swallowed up by the sun in a short time. In order to save themselves, human beings put forward a bold plan called "Wandering Earth", that is, pouring the global power to build tens of thousands of engines and steering gears on the surface of the earth, pushing the earth out of the solar system and rushing to another habitat after 2500 years.

China astronaut Liu Peiqiang went to the International Space Station when his son Liu Qi was four years old, and shouldered the heavy responsibility of being a navigator with his international counterparts. In a blink of an eye, Liu Qi grew up. He sneaked out of the water with his sister blossoming and stole grandpa Han Ziang's transport vehicle. As a result, he was not only arrested, but also suffered a global engine shutdown.

In order to repair the engine and prevent the earth from falling into Jupiter, the whole world began to carry out saturation rescue, and even Liu Qi and their cars were forced to join. In the race against time, countless people bravely followed each other, desperate to continue the hope of future generations.

5. Seek the help of the Great God, the physics principle of wandering the earth for five times.

Escape era: starting the engine means that the earth reaches the escape speed and flies out of the solar system.

Braking age: the earth engine is used to stop the earth's rotation and make the engine nozzle fixed in the opposite direction of the earth's operation.

This is death.

New solar age: Earth enters proxima centauri orbit and becomes a satellite of this star.

Humans have detected that the sun will be "sick" and expand so much that the earth will move inside the sun. In order to avoid the catastrophe from the sky, and for the continuation of mankind, United * * * decided to drive the earth to escape from the solar system and sail for proxima centauri. There, the Earth can stay in proxima centauri's satellite orbit and continue to exist as one of its satellites. And this time, it will take 2500 years, 100 generations.

Braking means stopping the earth from turning. Twelve thousand earth engines were installed on the Asian-American plain, and the whole braking era took 42 years. The earth stopped spinning. Since then, there has been no sunrise or sunset on the earth. Heroes were born after the brake era. At this time, human science and technology have developed to a certain height. Each of these earth engines is more than 10,000 meters high, using heavy elements for fusion and rocks as fuel.

At this time, the landscape on the earth is like this: the whole atmosphere has been heated to 70-80 degrees by the flame from the engine, and human beings must wear cooling clothes to move outdoors. The high temperature caused by the engine melted the glaciers, and the tides swallowed up two-thirds of the big cities in the northern hemisphere, such as Shanghai. The whole earth has changed beyond recognition before it started. Human values about the sun have also changed from worship to fear.
