Percentage of Hydrogen in earths atmosphere?
Hydrogen makes up about 0.000055% of Earth's atmosphere by volume. Although it is present in very small amounts compared to other gases like nitrogen and oxygen, it plays a crucial role in the chemistry and dynamics of the atmosphere.
What planet has a nitrogen- oxygen atmosphere?
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.
What process was primarily responsible for the development of the present percentage of free oxygen in the Earth's atmosphere?
The process primarily responsible for the development of the present percentage of free oxygen in the Earth's atmosphere is photosynthesis. This process is carried out by plants, algae, and cyanobacteria, which convert carbon dioxide and water into oxygen and glucose with the help of sunlight. Over time, this has led to the accumulation of oxygen in the atmosphere to its present level of around 21%.
