Earth's Atmosphere and Systems Concepts

The video explores Earth's systems, focusing on the atmosphere, hydrosphere, geosphere, and biosphere. It details the atmosphere's stratification into five layers: troposphere, stratosphere, mesosphere, thermosphere, and exosphere, each with unique characteristics and roles. The video emphasizes the importance of these layers in sustaining life, protecting from harmful radiation, and supporting communication.
