Gas Layer Structure

Earth's atmosphere consists of distinct layers defined by temperature and composition. The troposphere contains 75% of atmospheric mass and most weather phenomena. Nitrogen (78%) and oxygen (21%) dominate composition, with trace gases including argon, carbon dioxide, and water vapor.

Climate Regulation

Atmospheric gases regulate Earth's temperature through the greenhouse effect. CO2, methane, and water vapor trap heat, maintaining habitable conditions. Industrial emissions increase greenhouse gas concentrations, enhancing this effect and driving global warming.

Chemical Interactions

Complex chemical reactions occur throughout atmospheric layers. The ozone layer filters harmful UV radiation, while photochemical processes create and break down various compounds. Urban pollution and industrial emissions alter natural atmospheric chemistry, affecting air quality and climate stability.Shutdown123
