Question

Quizplus · Accepted Answer

Methane, carbon dioxide, water vapor, and ozone have variable concentrations in the atmosphere due to natural and human activities. The other gases listed have relatively stable concentrations. Nitrogen and oxygen make up the majority of the Earth's atmosphere, and argon is a noble gas that is largely inert. Hydrogen is a very small component of the atmosphere and is not typically found in significant concentrations.
