Answer 1

yes nitrogen Is abundant in the earth's atmosphere. .it's 78% of the earth's atmosphere. ..

Answer 2

The most abundant gas in the Earth's atmosphere is nitrogen, which is about 78%.

Explanation:

• Oxygen is the next most abundant gas, present at 20 to 21%.
• Although humid air appears to contain a lot of water, the maximum amount of water vapor in the air can be only 4%.
• Although there is a relatively uniform chemical structure in the atmosphere near the surface, the abundance of gas varies at higher altitudes.
• Nitrogen is removed from the atmosphere and deposited on the earth's surface by means of special nitrogen fixing bacteria and by rainwater.
• Oxygen is exchanged between atmosphere and life through the process of photosynthesis and respiration.
• Water vapor converts to a concentration in the spatial and temporal atmosphere.
• The highest concentrations of water vapor are found in oceans and tropical rainforests near the equator.
• The fifth most abundant gas is carbon dioxide.
