Interactions of Earth's Spheres

The video tutorial explores the spheres of ecology: geosphere, atmosphere, hydrosphere, and biosphere. It explains how each sphere functions and interacts with others, highlighting processes like plate tectonics, erosion, photosynthesis, and cellular respiration. The tutorial emphasizes the interconnectedness of these spheres in supporting life on Earth.
