Earth's Atmosphere and Structure Concepts

The video explains Earth's structure, including its shape and components: atmosphere, lithosphere, and hydrosphere. It details the layers of the atmosphere, the structure of the lithosphere, and tectonic plate movements. The hydrosphere and the water cycle are also covered. The video concludes with a reminder of the importance of understanding Earth's structure for safety during natural disasters.
