A study led by Wei Shi from Chengdu University of Technology suggests that changes in the subduction of tectonic plates may correlate with increases in Earth's oxygen levels. The research indicates that multiple factors contributed to the rise of oxygen in the atmosphere over billions of years, including the role of photosynthetic life and geological processes that facilitate the exchange of oxygen between the atmosphere and the Earth's interior.

Study Links Plate Tectonics to Earth's Oxygen Levels
Researchers have found a potential link between tectonic plate subduction and the increases in Earth's atmospheric oxygen levels. The study suggests that both biological and geological processes played significant roles in the evolution of the planet's oxygen-rich atmosphere.
