The video explains Earth's interconnected systems: atmosphere, lithosphere, hydrosphere, and biosphere. It details the composition and functions of each system, such as the atmosphere's role in protecting life and the hydrosphere's water coverage. The biosphere encompasses all life, while the lithosphere includes Earth's crust and tectonic activity. The video highlights how these systems interact to sustain life on Earth.
