Östersund vs Earth

Informations

Östersund (pronounced [œstɛˈʂɵnːd] (listen); Southern Sami: Staare) is an urban area (city) in Jämtland in the middle of Sweden. It is the seat of Östersund Municipality and the capital of Jämtland County. Östersund is located at the shores of Sweden's fifth largest lake, Storsjön, opposite the island Frösön, and is the only city in Jämtland. Östersund is the region's cultural and economical centre and by tradition a city of trade and commerce. Östersund had one of the most extensive garrisons in Sweden prior to its closure in the early-21st century. The city is the Mid Sweden University's largest campus site with approximately 7,000 students. With a total population of 50,960 (2017) Östersund is the 22nd most populous city in Sweden, the 46th most populous city in Scandinavia, and by far the largest inland city in Northern Sweden. The city was the only Swedish city founded and chartered in the 18th century. Östersund was founded in order to create a trade monopoly over Jämtland whose inhabitants' lucrative trade annoyed the Swedish crown. The intention was to persuade the local farmers to deliver merchandise to middlemen in Östersund, but the population opposed this economic philosophy, and Östersund long remained small. It took until the end of the 19th century for Östersund to truly become a city, after the arrival of the railroad and the economic liberalization of that time.

Östersund is situated in inland Scandinavia and connected to Sundsvall in the east on the Swedish coast, and Trondheim in the west at the shores of the Norwegian Sea. Östersund is located in the middle of Scandinavia, in the middle of Sweden, in the middle of Jämtland County and in the middle of Östersund Municipality. As the most centrally located city in Sweden, the city credits itself as the centre of Sweden.Östersund is marketed as Vinterstaden – Winter City. Winter City as a project is run by the Municipality together with city enterprises. Östersund has had a long history as a centre of outdoor activities with a modern cross-country ski stadium and an actual piste in the city itself. Östersund has also hosted several World Championships in various sports such as biathlon, speed skating and ski orienteering along with Swedish National Championships in cross country skiing and snocross. The city has been the applicant city of Sweden for several Winter Olympic Games, but has yet to host one. The precursor to the Winter Olympic Games, the Nordic Games, were however held at several occasions in the city, due to lack of snow in Stockholm.

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.
