Earth vs Wuhan

Informations

Earth is the third planet from the Sun and the only astronomical object known to harbor life. About 29% of Earth's surface is land consisting of continents and islands. The remaining 71% is covered with water, mostly by oceans but also lakes, rivers and other fresh water, which together constitute the hydrosphere. Much of Earth's polar regions are covered in ice. Earth's outer layer is divided into several rigid tectonic plates that migrate across the surface over many millions of years. Earth's interior remains active with a solid iron inner core, a liquid outer core that generates Earth's magnetic field, and a convecting mantle that drives plate tectonics. According to radiometric dating estimation and other evidence, Earth formed over 4.5 billion years ago. Within the first billion years of Earth's history, life appeared in the oceans and began to affect Earth's atmosphere and surface, leading to the proliferation of anaerobic and, later, aerobic organisms. Some geological evidence indicates that life may have arisen as early as 4.1 billion years ago. Since then, the combination of Earth's distance from the Sun, physical properties and geological history have allowed life to evolve and thrive. In the history of life on Earth, biodiversity has gone through long periods of expansion, occasionally punctuated by mass extinctions.

Over 99% of all species that ever lived on Earth are extinct. Almost 8 billion humans live on Earth and depend on its biosphere and natural resources for their survival. Humans increasingly impact Earth's hydrology, atmospheric processes and other life. Earth's atmosphere consists mostly of nitrogen and oxygen. Tropical regions receive more energy from the Sun than polar regions, which is redistributed by atmospheric and ocean circulation. Greenhouse gases also play an important role in regulating the surface temperature. A region's climate is not only determined by latitude, but also by its proximity to moderating oceans and height among other factors. Extreme weather, such as tropical cyclones and heat waves, occurs in most areas and has a large impact on life. Earth's gravity interacts with other objects in space, especially the Sun and the Moon, which is Earth's only natural satellite. Earth orbits around the Sun in about 365.25 days. Earth's axis of rotation is tilted with respect to its orbital plane, producing seasons on Earth. The gravitational interaction between Earth and the Moon causes tides, stabilizes Earth's orientation on its axis, and gradually slows its rotation. Earth is the densest planet in the Solar System and the largest and most massive of the four rocky planets.

Wuhan (simplified Chinese: 武汉; traditional Chinese: 武漢, [ù.xân] (listen)) is the capital of Hubei Province in the People's Republic of China. It is the largest city in Hubei and the most populous city in Central China, with a population of over 11 million, the ninth-most populous Chinese city and one of the nine National Central Cities of China.The name "Wuhan" came from the city's historical origin from the conglomeration of Wuchang, Hankou and Hanyang, which are collectively known as the "Three Towns of Wuhan" (武汉三镇). It lies in the eastern Jianghan Plain, at the confluence of the Yangtze river and its largest tributary, the Han River and is known as "Nine Provinces' Thoroughfare" (九省通衢).Wuhan is considered by some to be one of the potential sites of the pivotal Battle of the Red Cliffs, which stopped warlord Cao Cao's incursion into southern China at the end of the Eastern Han dynasty. Other historical events taking place in Wuhan include the Wuchang Uprising of 1911, which led to the downfall of the Qing dynasty and the establishment of the Republic of China. Wuhan was briefly the capital of China in 1927 under the left wing of the Kuomintang (KMT) government led by Wang Jingwei. The city later served as the wartime capital of China for ten months in 1937 during the Second Sino-Japanese War. SARS-CoV-2, a novel coronavirus that caused the COVID-19 pandemic, was first identified in Wuhan in December 2019.Wuhan is considered the political, economic, financial, commercial, cultural and educational center of Central China. It is a major transportation hub, with dozens of railways, roads and expressways passing through the city and connecting to other major cities. Because of its key role in domestic transportation, Wuhan is sometimes referred to as "the Chicago of China" by foreign sources.

The "Golden Waterway" of the Yangtze River and the Han River traverse the urban area and divide Wuhan into the three districts of Wuchang, Hankou and Hanyang. The Wuhan Yangtze River Bridge crosses the Yangtze in the city. The Three Gorges Dam, the world's largest power station in terms of installed capacity, is located nearby. Historically, Wuhan has suffered risks of flooding, prompting the government to alleviate the situation by introducing ecologically friendly absorption mechanisms.While Wuhan has been a traditional manufacturing hub for decades, it is also one of the areas promoting modern industrial changes in China. Wuhan consists of three national development zones, four scientific and technological development parks, over 350 research institutes, 1,656 high tech enterprises, numerous enterprise incubators and investments from 230 Fortune Global 500 firms. It produced GDP of US$22.4 billion in 2018. The Dongfeng Motor Corporation, an automobile manufacturer, is headquartered in Wuhan. The city is home to multiple notable institutes of higher education, including Wuhan University and the Huazhong University of Science and Technology. Wuhan is also one of the top city in the world by scientific research and it ranks 13th globally and 4th in China (after Beijing, Shanghai and Nanjing). In 2017, Wuhan was designated as a Creative City by UNESCO, in the field of design. Wuhan is classified as a Beta- (global second tier) city together with other 7 cities in China, including Changsha, Dalian, Jinan, Shenyang, Xiamen, Xi'an and Zhengzhou by the Globalization and World Cities Research Network.
