Air Composition Insights

Early Earth had minimal fire due to low oxygen levels, but as oxygen increased, so did the potential for combustion. While nitrogen, oxygen, and argon dominate our atmosphere, carbon dioxide plays a crucial role in insulating the planet and supporting plant life, despite its minuscule presence. Additionally, neon, another noble gas, originates from both primordial sources and radioactive decay, highlighting the complex interplay of elements in our air.
