Earths atmosphere is rich in Oxygen, some 21% of the air is Oxygen. There is oxygen on other planets, but the percentage comes nowhere close to this. The percentage of Oxygen in earths atmosphere is thought to have been much higher in the past, before animals were about, but after the arrival of plants.
The earths atmosphere is made up of 78% nitrogen and 21% oxygen
The earths atmosphere is made up of 78% nitrogen and 21% oxygen
The Earth's atmosphere contains 78% nitrogen.
32% the of the atmosphere is Argon, Oxygen and Other stuff
if ther will be too much nitrogen so oxygen will decrease and we will be breathless .
the Martian atmosphere is made up of 95% Carbon Dioxide, 3% nitrogen, 1.6% argon, and 0.4% oxygen.
21% Oxygen, 78% Nitrogen, 1% other gasses in out atmosphere.
Close to 21%, near 20.95%.
The earths atmosphere is made up of 78% nitrogen and 21% oxygen
Together about 5 thousand trillion tonnes. About 1 thousand trillion tonnes is oxygen and 4 thousand trillion tonnes is nitrogen.
The main components of the atmosphere are: Nitrogen (approximately 78%) Oxygen (approximately 21%) Argon (approximately 0.93%) Carbon Dioxide (approximately 0.038%) Along with other gases of a much smaller proportion.
