Earth vs Lyon

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.

Lyon or Lyons (UK: , US: , French: [ljɔ̃] (listen); Francoprovençal: Liyon, pronounced [ʎjɔ̃]; Italian: Lione, pronounced [liˈone]) is the third-largest city and second-largest urban area of France. It is located at the confluence of the rivers Rhône and Saône, about 470 km (292 mi) south-east of Paris, 320 km (199 mi) north of Marseille and 56 km (35 mi) northeast of Saint-Étienne. Inhabitants of the city are called Lyonnais. The city of Lyon proper had a population of 516,092 in 2017 within its small municipal territory of 48 km2 (19 sq mi), but together with its suburbs and exurbs the Lyon metropolitan area had a population of 2,323,221 that same year, the second-most populated in France. The city of Lyon and 58 suburban municipalities have formed since 2015 the Metropolis of Lyon, a directly elected metropolitan authority now in charge of most urban issues, with a population of 1,385,927 in 2017.Lyon is the capital of the region of Auvergne-Rhône-Alpes as well as the seat of the Rhône departmental council (whose jurisdiction, however, no longer extends over the Metropolis of Lyon since 2015). Former capital of the Gauls at the time of the Roman Empire, Lyon is the seat of an archbishopric whose holder bears the title of Primate of the Gauls.

Lyon became a major economic hub during the Renaissance. The city is recognized for its cuisine and gastronomy, and historical and architectural landmarks; as such, the districts of Old Lyon, the Fourvière hill, the Presqu'île and the slopes of the Croix-Rousse are inscribed on the UNESCO world heritage list. Lyon was historically an important area for the production and weaving of silk. Lyon played a significant role in the history of cinema: it is where Auguste and Louis Lumière invented the cinematograph. It is also known for its light festival, the Fête des Lumières, which begins every 8 December and lasts for four days, earning Lyon the title of Capital of Lights. Economically, Lyon is a major centre for banking, as well as for the chemical, pharmaceutical, and biotech industries. The city contains a significant software industry with a particular focus on video games, and in recent years has fostered a growing local start-up sector. Lyon hosts the international headquarters of Interpol, the International Agency for Research on Cancer and Euronews. According to the Globalization and World Rankings Research Institute, Lyon is considered a Beta city, as of 2018. It ranked second in France and 40th globally in Mercer's 2019 liveability rankings.
