Completing Earth's Spheres: The Hydrosphere and Atmosphere Explained

The video explores Earth's four spheres, focusing on the hydrosphere and atmosphere. It explains the components of the hydrosphere, including oceans, lakes, rivers, and glaciers, and describes the atmosphere's layers, such as the troposphere and stratosphere. The video concludes with a practical example at the beach, illustrating the interaction between the hydrosphere and atmosphere.
