The top two gases found in the Earth's atmosphere are nitrogen, which makes up about 78% of the atmosphere, and oxygen, accounting for approximately 21%. Together, these two gases dominate the atmospheric composition, with trace amounts of other gases such as argon, carbon dioxide, and water vapor making up the remainder. Nitrogen plays a crucial role in various biological processes, while oxygen is essential for respiration in most living organisms.

What two gases are found in greater amounts?

In nature, the two most common gases are Nitrogen and Oxygen. Air is about 78% N2, 21% O2, and 1% everything else (Hydrogen, Helium, Argon, etc.)


What are then two main gases found in earths atmosphere?

The two main gases are Nitrogen (N2) and Oxygen (O2), which comprise around 78% and 21% of the atmosphere by volume respectively. The remaining 1% is mostly Argon (Ar), followed by Carbon Dioxide (CO2) as well as several other gases present in trace amounts. All of these figures are for dry air, however water vapour (H2O) is also present in air at levels of up to 4%, but this is highly variable depending on localised conditions, and it makes up a lower percentage of the atmosphere as a whole.
