Do you know?
The Earth's atmosphere is mostly nitrogen (78%) and oxygen (21%). Other gases like carbon dioxide and argon help with breathing, plants and weather. Tap to read more.
Nitrogen Dominance
Nitrogen makes up about 78% of Earth's atmosphere, making it the primary gas. It is vital for maintaining atmospheric balance and stability.
Oxygen's Role
Oxygen is the second most abundant gas, comprising 21% of the atmosphere. It is essential for the survival of most living organisms.
Stability
Nitrogen's stability prevents it from reacting easily with other elements, contributing to a stable atmosphere. This stability is key for a safe environment.
Life Essential
While plants rely on carbon dioxide for photosynthesis, they also need nitrogen for growth. Nitrogen supports ecosystems and plant development.
Atmospheric Pressure
Nitrogen helps maintain atmospheric pressure, supporting weather systems and flight dynamics. It ensures conditions necessary for Earth's climate patterns.
Balance of Gases
Nitrogen helps balance the reactive gases in the atmosphere, preventing rapid combustion. This balance reduces the risk of uncontrolled fires.
