Earth's Interconnected Systems: Atmosphere, Hydrosphere, Lithosphere, and Biosphere

The video explains Earth's interconnected systems: atmosphere, lithosphere, hydrosphere, and biosphere. Each system is defined, highlighting its components and functions. The atmosphere provides protection and essential gases, the hydrosphere covers Earth's water, the biosphere encompasses all life, and the lithosphere includes Earth's crust and tectonic activity. The video emphasizes the interdependence of these systems in maintaining life on Earth.
