Kinshasa vs Earth

Informations

Kinshasa (; French: [kinʃasa]; Lingala: Kinsásá), formerly Léopoldville (Dutch: Leopoldstad), is the capital and the largest city of the Democratic Republic of the Congo. The city is situated alongside the Congo River. Once a site of fishing and trading villages, Kinshasa is now a megacity with a population of about 16 million. It faces Brazzaville, the capital of the neighbouring Republic of the Congo, which can be seen in the distance across the wide Congo River, making them the world's second-closest pair of capital cities after Rome and Vatican City. The city of Kinshasa is also one of the DRC's 26 provinces. Because the administrative boundaries of the city-province cover a vast area, over 90 percent of the city-province's land is rural in nature, and the urban area occupies a small but expanding section on the western side.

Kinshasa is Africa's third-largest urban area after Cairo and Lagos. It is also the world's largest Francophone urban area (surpassing Paris in population), with French being the language of government, schools, newspapers, public services, and high-end commerce in the city, while Lingala is used as a lingua franca in the street. Kinshasa hosted the 14th Francophonie Summit in October 2012.Residents of Kinshasa are known as Kinois (in French and sometimes in English) or Kinshasans (English). The indigenous people of the area include the Humbu and Teke.

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.
