Nitrogen gas makes up about 78% of Earth's atmosphere today. However, human activities have altered the nitrogen cycle by increasing the amount of reactive nitrogen in the environment through processes like fertilizer use and fossil fuel combustion, which can lead to environmental issues like air and water pollution.
Earth's early atmosphere was first changed through volcanic activity, which released gases such as water vapor, carbon dioxide, and nitrogen. This led to the formation of oceans and the gradual accumulation of oxygen through photosynthesis by early organisms like cyanobacteria. This oxygenation process transformed the atmosphere to one more similar to the one we have today.
The main gases present in Earth's atmosphere today are nitrogen (about 78%), oxygen (about 21%), argon (about 0.93%), and carbon dioxide (about 0.04%). Other gases such as water vapor, methane, and trace amounts of other gases are also present.
The main gases in Earth's atmosphere today are nitrogen (about 78%) and oxygen (about 21%). Other important gases include argon, carbon dioxide, and trace amounts of water vapor, methane, and ozone.
to those found in volcanic eruptions today, such as water vapor, carbon dioxide, and nitrogen. These gases were likely released from the Earth's interior through volcanic activity. Over time, the atmosphere changed as oxygen levels rose due to photosynthetic organisms.
The Earth's atmosphere is primarily composed of nitrogen (about 78%) and oxygen (about 21%). Other gases, such as argon, carbon dioxide, and trace amounts of other gases, make up the remaining composition.
The earths atmosphere has significantly altered over the years. The process of the earth's atmosphere was recognized and evolved 2.7 billion years ago, forming the nitrogen-oxygen atmosphere that exists today. This change enabled the formation and beginning of the ozone layer (which along with magnetic fields) block solar radiation.

Almost no oxygen, lots of CO2, still mostly nitrogen.

your question is... How did the Earth`s atmosphere change composotion to became today`s nitrogen and oxygen atmosphere? Answer: it happend with the help of solar untraviolet (uv) radiation,the very thing what we worry about now for its cancer-causing ability

biogeochemistry is used by earths atmosphere
Today the Earth's atmosphere is being destroyed by all the pollution by cars and power plants.
Approximately 78% of the Earth's atmosphere is composed of nitrogen.
No, the Nitrogen in the air has probably always been there (because nitrogen is rather inert), but originally Earths atmosphere was reducing (it had no free Oxygen) and probably contained large amounts of CO2 and hydrocarbons. The present atmosphere on Earth is the product of biological processes which have slowly introduced free Oxygen into the Oceans and then the atmosphere - life made Earth habitable for life!
