The atmosphere is primarily composed of Nitrogen (N2), which accounts for 78%. Oxygen follows, accounting for 20% of its volume, with argon less than 1%. The remainder is composed of particulates and trace gases, including water vapor.
Argon makes up roughly one percent of Earth's atmospheric gases. A more precise/exact amount would be 0.93%
Oxygen is the gas that makes up about 21 percent of the Earth's atmosphere.
Oxygen is the gas that accounts for about 20 percent of Earth's atmosphere.
Oxygen forms 21 percent of the Earth's atmosphere.
Around 80 percent of the gas in Earth's atmosphere is located in the troposphere, the layer closest to the Earth's surface where weather events occur and most of the atmosphere's mass is concentrated.
