Today's atmosphere is primarily composed of nitrogen (about 78%) and oxygen (around 21%), with trace amounts of argon, carbon dioxide, and other gases. Water vapor varies significantly, contributing to weather patterns and climate. Additionally, pollutants and greenhouse gases like methane and ozone are present, impacting air quality and environmental health. This composition is crucial for sustaining life and regulating the Earth's climate.

How did the primitive atmosphere differ from atmosphere today?

As opposed to today's atmosphere, the Earth's early atmosphere would have been quite impossible for human life to thrive in. Today the atmosphere consists primarily of Nitrogen, Oxygen, and Carbon Dioxide, but early Earth's first atmosphere was probably made of Hydrogen and Helium.

What would earths atmosphere likely consist mostly of without the presence of life?

If Earth did not have any life, its atmosphere would likely consist mostly of nitrogen, similar to the atmosphere of Mars or Venus. Volcanic activity would have likely contributed to the release of gases like carbon dioxide and water vapor. Sunlight and cosmic rays might also have influenced the composition of the atmosphere over time.
