nitrogen and oxygen
Oxygen and nitrogen are the two most abundant gases in the atmosphere. They make up 99% of the air.
The most abundant gases in dry air are nitrogen (about 78%) and oxygen (about 21%). These two gases make up the majority of Earth's atmosphere and are essential for supporting life. Other gases such as argon, carbon dioxide, and neon make up the remaining percentage in very small amounts.
The main gases in Earth's atmosphere are nitrogen, followed by oxygen.
hydrogen and nitrogen (I think)
Nitrogen (78%) and oyxgen (21%). Argon comprises just under 1%.
Nitrogen and oxygen make up the majority of the atmosphere, but there are other gases as well, such as carbon dioxide, ozone, and helium.
The two main components of Earth's atmosphere are nitrogen (about 78%) and oxygen (about 21%). Together, they make up the majority of the gases present in the atmosphere.
The two main gases found in the troposphere are nitrogen (about 78%) and oxygen (about 21%). These gases make up the majority of the Earth's atmosphere and are essential for supporting life.
nitrogen and oxygen
The most abundant gases in Earth's atmosphere today are nitrogen (about 78%) and oxygen (about 21%). These two gases make up the majority of our atmosphere, with other gases like argon, carbon dioxide, and water vapor present in smaller amounts.
The two main gases that make up the atmosphere of Uranus are hydrogen and helium. The atmosphere also contains ammonia and methane.
The two primary gases in the Earth's atmosphere are nitrogen and oxygen.
Nitrogen and oxygen make up the largest percentage of the atmosphere.
Nitrogen (which makes up about 78% of the atmosphere) and Oxygen (about 21%)
