Is air and atmosphere the same?
1. What is the difference between air and atmosphere? The Air is the gas mixture that forms the Earth’s atmosphere, which remains around our planet thanks to the attraction of the force of gravity. The atmosphere is the Earth’s gaseous region, the outermost and least dense region of the planet.
Earth’s atmosphere is a thin blanket of gases and tiny particles — together called air. We are most aware of air when it moves and creates wind. Atmospheric gases, especially carbon dioxide (CO2) and oxygen (O2), are extremely important for living organisms.
What is called atmosphere?
An atmosphere is the layers of gases surrounding a planet or other celestial body. Earth’s atmosphere is composed of about 78\% nitrogen, 21\% oxygen, and one percent other gases.

All living beings on earth depend on the atmosphere for their survival.
What is the makeup of the atmosphere?
About 78 percent of the Earth’s atmosphere consists of nitrogen, and oxygen makes up 21 percent. The remaining 1 percent is a combination of argon, water, carbon dioxide and other gases. The Earth’s atmosphere is the only atmosphere in the solar system where there is plentiful free oxygen.
What is the history of the atmosphere?
The origin of atmosphere is related to the origin of earth itself. The earth was formed by the accretion of solid materials that condensed from the solar nebula . The atmosphere at that time was totally different from the atmosphere today.
What percentage of gases make up the atmosphere?
The most abundant gases in the atmosphere are nitrogen at 78 percent and oxygen at 21 percent, while the trace gases methane, neon and helium make up around one-tenth of 1 percent of the atmosphere.
What is the atmosphere of Earth made of?
Atmosphere of Earth. It is made up mainly of nitrogen (78.1\%). It also has plentiful oxygen (20.9\%) and small amounts of argon (0.9\%), carbon dioxide (~ 0.035\%), water vapor, and other gases. The atmosphere protects life on Earth by absorbing (taking) ultraviolet rays from the sun. It makes our days cooler and our nights warmer.
