Air

Air is the mixture of gases that makes up Earth's atmosphere, primarily composed of nitrogen (about 78%) and oxygen (about 21%), with trace amounts of other gases such as argon, carbon dioxide, and water vapor. It is essential for life on Earth, providing the oxygen necessary for respiration and serving as a medium for various atmospheric processes. Air also plays a crucial role in weather and climate, regulating temperature through heat absorption and distribution, as well as in the water cycle through the transport of moisture. Additionally, air pollution, caused by human activities such as industrial emissions and vehicle exhaust, poses significant environmental and health risks, leading to concerns about air quality and its impacts on ecosystems and public health.
