The Earth's atmosphere is primarily composed of nitrogen (about 78%) and oxygen (around 21%). Other gases present in smaller amounts include argon, carbon dioxide, neon, and trace gases such as methane and hydrogen. Water vapor also varies in concentration but can be a significant component, influencing weather and climate. Together, these gases create a balanced environment essential for life.
The Earth's atmosphere.
It is believed that Sedna, a distant dwarf planet in our solar system, does not have a significant atmosphere due to its extreme distance from the sun. Therefore, it is unlikely to have any gases that make up an atmosphere similar to that of planets closer to the sun.
The current atmosphere is primarily composed of nitrogen (about 78%), oxygen (approximately 21%), and argon (around 0.93%). Trace gases, including carbon dioxide and others, make up the remaining fraction. This composition is essential for supporting life and regulating the Earth's climate.

atmosphere
Earth's atmosphere makes up a blanket or an envelope around it, which is a mixture of many gases.
there is 1.25 percent of inert gases in the atmosphere
The dominant atmospheric gases for Earth are nitrogen (78%) and oxygen (21%). Together, these two gases make up about 99% of Earth's atmosphere. Other gases such as argon, carbon dioxide, and water vapor make up the remaining 1%.
Nitrogen and Oxygen make up nearly 99% of the dry atmosphere.
No, oxygen makes up about 21% of Earth's atmosphere. Nitrogen is actually the most abundant gas, making up about 78% of the atmosphere.
Water vapor makes up 75% of all forcing and roughly 5% of our atmosphere. Carbon Dioxide makes up 5% to 20% of all forcing and 0.038% of our atmosphere. The remaining gases are Methane, Ozone and virtually any other gas made up of three or more atoms. They make up the difference.
Fifty percent of the gases that make up the atmosphere are found below an altitude of about 5.6 kilometers (18,000 feet) due to the Earth's gravitational pull. This region is known as the troposphere, where most weather phenomena occur and where the majority of gases are concentrated.
