It surrounds us during our entire lives, and we breathe it in and out from our first to our last moment. Without it, there would be no life on our planet. We are talking about one of the four elements, air. The air combines gases that make up the earth’s atmosphere. Dry air is mainly composed of two gases: Nitrogen (N2) is the primary air component at 78.08 percent. At 20.92 percent, oxygen (O2) is the second most crucial component.
Furthermore, air contains noble gases (0.93 percent in total), mainly argon, as well as helium, neon, krypton and xenon. In addition, carbon dioxide (CO2) makes up 0.037 percent, and is one of the main air components due to its importance for living organisms and the climate. The air also includes methane, hydrogen, nitrous oxide (laughing gas) and carbon monoxide. In this article of Gazettely, we will tell you nine interesting things about the air that you probably don’t know.
Many scientific journals have certified it: every adult makes up to 2.5 liters a day. We are talking about farts, a mix of nitrogen, CO2, hydrogen, gas and methane sulfur produced by bacteria in the colon – and emitted by human and animals. David Wilkinson of JM University in Liverpool claims that 200 million years ago, the dinosaurs with their “farts” helped raise the planet’s temperature.
