Earth's Spheres and Their Interactions

The video explores Earth's spheres: geosphere, biosphere, atmosphere, hydrosphere, and cryosphere. It explains their components and interactions, such as how living things (biosphere) interact with land (geosphere) and air (atmosphere). The hydrosphere includes all water forms, and the cryosphere covers Earth's ice. The video highlights the complex interactions between these spheres, especially during a hurricane, demonstrating erosion and the role of dunes in protecting the land.
