lightening bolts ionized air molecules and create nitrogen compounds which are then carried by rain water down to the earth.
Nitrogen-fixing bacteria would be responsible for the greatest bulk of fixed nitrogen.
Yes, Earth's atmosphere is about 78% nitrogen.
The main geological reservoir for nitrogen is in the Earth's atmosphere, where nitrogen exists predominantly as nitrogen gas (N2). Nitrogen gas makes up around 78% of the Earth's atmosphere.
The main gases in Earth's atmosphere are nitrogen, followed by oxygen.
The two major components of the earth's atmosphere are nitrogen and oxygen. There is also trace amounts of hydrogen, carbon dioxide, and other gases.
No, nitrogen does not dilute the oxygen in Earth's atmosphere. Nitrogen and oxygen are the two main components of Earth's atmosphere, with nitrogen making up about 78% and oxygen about 21%. They coexist in the atmosphere without one diluting the other.
The main reservoir of nitrogen in the biosphere is the atmosphere. Nitrogen gas (N2) makes up about 78% of Earth's atmosphere. Nitrogen is cycled through the biosphere by processes like nitrogen fixation, nitrification, and denitrification.
Oxygen and Nitrogen
Nitrogen and Oxygen
The 3 types of gases in Earth's atmosphere are argon, oxygen and nitrogen.
Nitrogen and Oxygen account for almost 99% of Earth's atmosphere.
Nitrogen is the main gas in earth's atmosphere, composing 78% of it by volume while oxygen is 21%.
Nitrogen (which makes up about 78% of the atmosphere) and Oxygen (about 21%)
