Question

Quizplus · Accepted Answer

Nitrogen and oxygen make up the majority of the Earth's atmosphere in the homosphere, with nitrogen being the most abundant gas and oxygen coming in second place. Argon comprises a much smaller percentage, followed by carbon dioxide and trace gases. Xenon is present in trace amounts and is not significant enough to be included in the list. PAN and hydrocarbons are not major components of the homosphere. Neon, while present in the atmosphere, is only present in trace amounts and is not significant enough to be listed in the top five gases in terms of percentage. Similarly, ozone is also only present in trace amounts, although it does play an important role in protecting the Earth from the sun's harmful UV radiation.
