Aurora vs Cleveland

Informations

An aurora (plural: auroras or aurorae), sometimes referred to as polar lights (aurora polaris), northern lights (aurora borealis), or southern lights (aurora australis), is a natural light display in the Earth's sky, predominantly seen in high-latitude regions (around the Arctic and Antarctic). Auroras are the result of disturbances in the magnetosphere caused by solar wind. These disturbances are sometimes strong enough to alter the trajectories of charged particles in both solar wind and magnetospheric plasma. These particles, mainly electrons and protons, precipitate into the upper atmosphere (thermosphere/exosphere).

The resulting ionization and excitation of atmospheric constituents emit light of varying color and complexity. The form of the aurora, occurring within bands around both polar regions, is also dependent on the amount of acceleration imparted to the precipitating particles. Precipitating protons generally produce optical emissions as incident hydrogen atoms after gaining electrons from the atmosphere. Proton auroras are usually observed at lower latitudes.

Cleveland ( KLEEV-lənd), officially the City of Cleveland, is a major city in the U.S. state of Ohio, and the county seat of Cuyahoga County. It is located on the southern shore of Lake Erie, across the U.S. maritime border with Canada and approximately 60 miles (100 kilometers) west of the Ohio-Pennsylvania state border. Cleveland is the largest city on the shores of Lake Erie and the largest metropolitan economy and population in Ohio. Metropolitan Cleveland, with a population of 2.8 million, comprises two US-defined metropolitan statistical areas (MSA), the Cleveland MSA and the Akron MSA. Its GDP is $171 Billion (2018), making it the 21st largest in the United States. The city proper, with an estimated 2019 population of 381,009, ranks 53rd-largest city in the United States, though its economy and population are fluid across individual municipal boundaries.Designated as a "Gamma -" global city by the Globalization and World Cities Research Network, Cleveland anchors the Cleveland–Akron–Canton Combined Statistical Area, the most populous combined statistical area in Ohio and the 15th largest in the U.

S., with a population of 3,515,646 in 2010. Cleveland was founded in 1796 near the mouth of the Cuyahoga River by General Moses Cleaveland, after whom the city was named. A port city, it grew into a major manufacturing center due to its location on both the river and the lake shore, as well as numerous canals and railroad lines. Cleveland's economy relies on diversified sectors such as manufacturing, financial services, healthcare, biomedicals, and higher education.The city's major cultural institutions include the Cleveland Museum of Art, the Cleveland Museum of Natural History, the Cleveland Orchestra, Playhouse Square, and the Rock and Roll Hall of Fame. Known as "The Forest City" among many other nicknames, Cleveland serves as the center of the Cleveland Metroparks nature reserve system.
