Abuja vs Aurora

Informations

Abuja () is the capital city of Nigeria situated in the centre of the country within the Federal Capital Territory (FCT). It's a planned city and was built mainly from the 1980s, replacing the nation's most populous city of Lagos as the capital on 12 December 1991. Abuja's geography is characterized by Aso Rock, a 400-metre (1,300 feet ) monolith left by water erosion. The Presidential Complex, National Assembly, Supreme Court and much of the city extend into the south of the rock. Zuma Rock, a 792-metre (2,598 feet ) monolith, lies just north of the city on the expressway to Kaduna. At the 2006 census, the city of Abuja had a population of 776,298 which makes it among the ten most populous cities in Nigeria. According to the United Nations, Abuja climbed by 139.7% between 2000 and 2010, which makes it the fastest growing city in the world. As of 2015, the town is experiencing an annual growth of 35%, retaining its position as the weakest city on the African continent and among the fastest-growing in the world.

As of 2016, the metropolitan area of Abuja is estimated at six million individuals, placing it behind only Lagos as the most populous metro area in Nigeria.Major religious websites include the Nigerian National Mosque and the Nigerian National Christian Centre. The town is served by the Nnamdi Azikiwe International Airport. Abuja is known for being among the few purpose-built capital cities in Africa, in addition to being among those wealthiest.Abuja is Nigeria's political and administrative centre. It is also an integral capital on the African continent due to Nigeria's geo-political influence in regional affairs. Abuja is also a conference centre and hosts various meetings annually, like the 2003 Commonwealth Heads of Government meeting and the 2014 World Economic Forum (Africa) meetings.

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.
