photosynthesis
The levels of carbon dioxide have changed since the early Earth's atmosphere due to various factors such as volcanic activity, changes in ocean chemistry, and the evolution of plants. Over time, these factors have influenced the balance of carbon dioxide in the atmosphere, leading to fluctuations in its levels.
The earth's atmosphere has changed significantly over millions of years due to various factors such as volcanic activity, changes in the Earth's orbit, and the evolution of living organisms. For example, early Earth had a different composition with high levels of carbon dioxide and little oxygen. Over time, the atmosphere changed to its current composition with nitrogen as the dominant gas and oxygen supporting life.
During the Precambrian time, the Earth's atmosphere lacked free oxygen, and the early atmosphere was likely composed of gases such as methane, ammonia, and carbon dioxide. Throughout the Precambrian, there were significant changes in atmospheric composition due to volcanic activity and the evolution of photosynthetic organisms that contributed oxygen to the atmosphere.
Oxygen became part of Earth's atmosphere mainly as a result of the evolution of life forms, particularly through photosynthesis by early cyanobacteria and plants. This process involved converting carbon dioxide into oxygen as a byproduct, leading to the oxygen-rich atmosphere we have today.
The Earth's atmosphere has changed over time due to various factors such as volcanic activity, changes in greenhouse gas concentrations, and natural variations in solar radiation. Human activities, such as the burning of fossil fuels and deforestation, have also significantly impacted the composition of the atmosphere, leading to an increase in greenhouse gas emissions and global warming.

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.
how do geologists think earths atmosphere is formed

When a spacecraft goes into space its speed increases dramatically once it leave the earths atmosphere. When it is returning to earth, it hits the atmosphere at a faster rate than it was traveling when it left. The friction of the atmosphere against the craft, heats it up.
