Air is a mixture of gases. The mixture is unique and contains group of gases that is nearly constant within our atmosphere.
To simplify,
But Air isn’t just gas. Air also has tiny particles called aerosols. Aerosols come in many shapes and sizes, for example dust and pollen. These are natural aerosols that get moved by the wind. Air is also susceptible of other types of aerosols (like soot and smoke) that can be harmful to humans and cause air pollution. To add to the diversity of it all, there is something called bioaerosols. These are microbes that can’t fly, but can travel enormous distance like its non biological counterparts, due to wind, rain and biological discharges, like say, a sneeze.
Carbon Dioxide (CO2) is part of air. It can actually be a good thing too! It is what plants need to breathe, and they exhale Oxygen-2. We have a symbiotic relationship going on between Fauna & Flora. The problem is when we have excess CO2 because it accumulates within our atmosphere. When this happens it traps the sun’s heat energy in the atmosphere warming the planet and the oceans. The planet is a…
