Earth's Spheres and Their Interactions

Ranger Elizabeth from Floyd's Fort explains how Earth's materials are divided into four spheres: biosphere, geosphere, hydrosphere, and atmosphere. Each sphere is explored in detail, highlighting their components and interactions. The video emphasizes the interconnectedness of these spheres, using examples like trees and the water cycle to illustrate their interactions. The tutorial concludes with a review of the spheres and their significance in everyday life.
