Layers of the Atmosphere and Earth's Systems

The video tutorial explores Earth's four spheres: atmosphere, hydrosphere, geosphere, and biosphere. It details the layers of the atmosphere, the composition of air, and the role of carbon dioxide in global warming. The hydrosphere section covers the water cycle and the distribution of Earth's water. The geosphere is explained through its layers: core, mantle, and crust, highlighting plate tectonics. Finally, the biosphere is discussed, emphasizing the interconnectedness of life and Earth's systems.
