GCSE Chemistry - Evolution of the Atmosphere #67

The video explains the evolution of Earth's atmosphere, starting with volcanic activity that created a carbon dioxide-rich environment. Over billions of years, photosynthesis by algae and plants reduced CO2 levels and increased oxygen, enabling complex life. Carbon was sequestered in sedimentary rocks and fossil fuels, shaping today's atmosphere of mostly nitrogen and oxygen.
