The Earth's atmosphere is primarily composed of nitrogen (about 78%) and oxygen (about 21%). Other gases present in smaller amounts include argon (approximately 0.93%), carbon dioxide (around 0.04%), and trace gases such as neon, helium, methane, and hydrogen. Water vapor is also a significant component, varying in concentration.
