Atmospheric evolution is the study of the changes that have occurred in Earth's atmosphere over time. This research area examines how the composition, structure, and dynamics of the atmosphere have evolved due to various factors such as the presence of life, geological processes, and human activities. Scientists study the evolution of the atmosphere to better understand its past conditions and how it may continue to change in the future. This research is crucial for understanding climate change, air quality, and the overall health of our planet.
