The atmosphere of Earth is a layer of gases surrounding the planet Earth that is retained by Earth's gravity. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night (the diurnal temperature variation).

Atmospheric stratification describes the structure of the atmosphere, dividing it into distinct layers, each with specific characteristics such as temperature or composition. The atmosphere has a mass of about 5×10¹⁸ kg, three quarters of which is within about 11 km (6.8 mi; 36,000 ft) of the surface. The atmosphere becomes thinner and thinner with increasing altitude, with no definite boundary between the atmosphere and outer space. An altitude of 120 km (75 mi) is where atmospheric effects become noticeable during atmospheric reentry of spacecraft. The Kármán line, at 100 km (62 mi), also is often regarded as the boundary between atmosphere and outer space.

Olubankole Wellington (born March 27, 1981), known under the stage name Banky W, is an American Nigerian R&B artist.

Wellington was born in the United States to Nigerian parents, but the family moved back to Lagos Nigeria when he was five years old where he began singing in his church choir at the age of 8. After completing his secondary school Education at Home Science Association Secondary School, he moved to New York to attend college on a scholarship; earning a degree in Engineering at Rensselaer Polytechnic Institute. While still in college, he won the 'Albany Idol' competition, which catapulted him into the spotlight. He overcame many personal trials and obstacles to quickly become an in-demand artist on the local music scene; performing alongside major acts on tour. He wowed audiences with his silky smooth voice while building a loyal following; he established the Empire Mates Entertainment (E.M.E.) record label as a platform to get his music to his fans and began work on an EP.

Under the name Banky W, he released the EP Undeniable in 2003, as the first release on his jointly owned E.M.E Records. The EP was released on his own label, and was sold on the internet and out of the trunks of cars. The buzz around the album caught the ears of the executives at Fox 23 News New York who promptly dispatched a reporter with a camera crew to investigate the phenomenon sweeping the area. They were surprised it was a three person company executing a highly successful grassroots marketing campaign. The report became a two part special they aired leading to a distribution deal with TransWorld (Coconut's, Warehouse Music, Spec's Music); one of North America's largest music distributors. It became one of the top selling independent records, won him the 2003 R&B/Soul Artist of the Year at the Urban Independent Music Awards.His career was for a while threatened by cancer in the shoulder, but he managed to make a recovery from the illness.
