Understanding Earth's Spheres

The video explores Earth's four spheres: geosphere, biosphere, hydrosphere, and atmosphere. It delves into the hydrosphere, covering all water on Earth, and the atmosphere, detailing its layers and gases. The video concludes with a practical look at these spheres at the beach, highlighting their interactions.
