Earth vs Cincinnati

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.

Cincinnati ( SIN-sih-NAT-ee) is a major city in the U.S. state of Ohio and the government seat of Hamilton County. Settled in 1788, the city is located at the northern side of the confluence of the Licking and Ohio rivers, the latter of which marks the state line with Kentucky. The city is the economic and cultural hub of the Cincinnati metropolitan area, the fastest growing economic power in the Midwestern United States based on increase of economic output, which had a population of 2,190,209 as of the 2018 census estimates. This makes it Ohio's largest metropolitan area and the nation's 29th-largest. With a city population estimated at 303,940, Cincinnati is the third-largest city in Ohio and 64th in the United States. Cincinnati is within a day's drive of 49.70% of the United States populace, ranking it as fourth in the list of metro areas with the largest population base within one day's drive time.In the 19th century, Cincinnati was an American boomtown in the middle of the country. Throughout much of the 19th century, it was listed among the top 10 U.S. cities by population, surpassed only by New Orleans and the older, established settlements of the United States eastern seaboard, as well as being the sixth-biggest city for a period spanning 1840 until 1860. Cincinnati was the first city founded after the American Revolution, as well as the first major inland city in the country. Cincinnati developed with fewer immigrants and less influence from Europe than East Coast cities in the same period.

However, it received a significant number of German-speaking immigrants, who founded many of the city's cultural institutions. By the end of the 19th century, with the shift from steamboats to railroads drawing off freight shipping, trade patterns had altered and Cincinnati's growth slowed considerably. The city was surpassed in population by other inland cities, particularly Chicago, which developed based on strong commodity exploitation, economics, and the railroads, and St. Louis, which for decades after the Civil War served as the gateway to westward migration. Cincinnati is home to three major sports teams: the Cincinnati Reds of Major League Baseball; the Cincinnati Bengals of the National Football League; and FC Cincinnati of Major League Soccer. The city's largest institution of higher education, the University of Cincinnati, was founded in 1819 as a municipal college and is now ranked as one of the 50 largest in the United States. Cincinnati is home to historic architecture with many structures in the urban core having remained intact for 200 years. In the late 1800s, Cincinnati was commonly referred to as the "Paris of America", due mainly to such ambitious architectural projects as the Music Hall, Cincinnatian Hotel, and Shillito Department Store. Cincinnati is the birthplace of William Howard Taft, the 27th President of the United States.
