In what ways is N2 gas removed from the atmosphere?
1. Nitrogen gas (N2) can be removed from the atmosphere through biological processes carried out by certain bacteria, such as nitrogen-fixing bacteria. These bacteria are able to convert atmospheric nitrogen into a form that can be used by plants and other organisms.
2. Industrial processes, such as the Haber-Bosch process, can also remove nitrogen gas from the atmosphere. This process involves using high temperatures and pressures to convert atmospheric nitrogen into ammonia, which is then used as a fertilizer.
3. Some natural processes, such as lightning strikes, can also cause nitrogen gas to react with other elements in the atmosphere and form compounds that are eventually removed from the atmosphere through precipitation.
4. In certain environmental conditions, nitrogen gas can also be absorbed by the soil and other surfaces, effectively removing it from the atmosphere.
