õhumolekulid

õhumolekulid refers to the individual molecules that collectively make up the Earth's atmosphere. The atmosphere is a complex mixture of gases, and its primary constituents are nitrogen (N2) and oxygen (O2) molecules, which together account for approximately 99% of dry air. Nitrogen molecules, comprising about 78% of the atmosphere, are relatively inert. Oxygen molecules, making up about 21%, are crucial for respiration and combustion.

Beyond these dominant gases, trace amounts of other õhumolekulid are also present, playing significant roles in atmospheric processes. Argon (Ar), an inert gas, constitutes about 0.9%. Carbon dioxide (CO2) molecules, though present in much smaller concentrations (around 0.04%), are vital greenhouse gases that influence Earth's temperature. Water vapor (H2O) molecules are another important component, with their concentration varying significantly depending on location and temperature, and are essential for weather phenomena and the water cycle.

Other õhumolekulid found in the atmosphere include ozone (O3), methane (CH4), nitrous oxide (N2O), and various pollutants. These molecules, even in minute quantities, can have profound effects on atmospheric chemistry, climate, and air quality. The constant motion and interactions of these õhumolekulid create the dynamic environment we experience as weather and climate. Their properties, such as size, mass, and reactivity, determine their behavior and influence within the atmosphere.
