ESS2E - Biogeology

The video explores biogeology, focusing on how life interacts with Earth's spheres: geosphere, hydrosphere, atmosphere, and biosphere. It discusses how life, such as cyanobacteria, has historically impacted Earth's environment, including the carbon and nitrogen cycles. The video outlines teaching strategies for different educational levels, emphasizing the importance of understanding environmental changes and evolution. It highlights examples like dinosaurs and mammals to illustrate adaptation and coevolution, stressing the continuous interaction between life and Earth's changing landforms.
