No. Not across the whole planet. The concentrations of some of the gases, particularly water vapor, vary from one area to the next.
Air is considered homogenous because it is composed of a mixture of gases (mainly nitrogen, oxygen, argon, and carbon dioxide) that are evenly distributed throughout the atmosphere. This means that the properties of air, such as temperature and pressure, are relatively uniform in different parts of the atmosphere.
Air is considered homogenous because it is a mixture of gases (primarily nitrogen and oxygen) that are evenly distributed throughout the atmosphere. This means that the composition of air is relatively consistent and uniform, with no noticeable variations in its properties in different locations or at different altitudes.
