When the universe came into existence, the only elements were mainly hydrogen and helium. Some time afterwards, stars formed and started to burn hydrogen in a nuclear furnace. As this happens the hydrogen combines to form helium. This is the process which occurs in our own sun that is also just a star. As the sun and other stars run out of hydrogen the core collapses, the temperature increases and helium starts to burn to form heavier elements. Small stars form red giants and then simply fade away but if the star is large enough they go out with a bang called a supernova. This returns a lot of the star's mass to the universe in the form of larger atoms before the remainder forms and falls into a black hole. Some time later when new stars form and planets form around them, they contain these heavier elements remnants of earlier stars. All of the heavier elements on earth had their origins is such supernova stars. Nitrogen is the largest component of the atmosphere. Phosphorus is mined as phosphate.

Where did the nitrogen in today's air come from?

The nitrogen in today's air primarily comes from the atmosphere's original composition, which was formed during the Earth's early history by volcanic activity and meteorite impacts. Over time, nitrogen-fixing bacteria in soil and water have also played a significant role in converting atmospheric nitrogen into forms that can be utilized by living organisms.


What percentage of nitrogen is in the air today?

Approximately 78% of the Earth's atmosphere is composed of nitrogen.


Where does sulfur oxides and nitrogen oxides in the air come from?

Sulfur oxides and nitrogen oxides in the air primarily come from the burning of fossil fuels in vehicles, power plants, and industrial processes. When fuel containing sulfur and nitrogen is burned, these elements combine with oxygen in the air to form sulfur oxides (SOx) and nitrogen oxides (NOx), which are then released into the atmosphere.

Where does nitrogen in air come from?

Nitrogen in the air comes from two main sources: volcanic activity and biological processes. Volcanic eruptions release nitrogen into the atmosphere, while living organisms and certain bacteria convert nitrogen from the soil into a form that can be used by plants, which then release it back into the air through processes like respiration and decay.
