Exploring Earth's Four Systems: Hydrosphere, Atmosphere, Geosphere, and Biosphere

The video tutorial explores Earth's four systems: hydrosphere, atmosphere, geosphere, and biosphere. It details each system's characteristics, such as the hydrosphere's water distribution, the atmosphere's protective layers, the geosphere's rock formations, and the biosphere's life forms. The tutorial emphasizes the interdependence of these systems, highlighting how they transfer energy and matter to sustain Earth's functions.
