Exploring Earth's Five Spheres

The video tutorial discusses Earth's system, composed of five main spheres: geosphere, atmosphere, hydrosphere, cryosphere, and biosphere. Each sphere has unique characteristics and components, such as rocks and minerals in the geosphere, gases in the atmosphere, liquid water in the hydrosphere, solid water in the cryosphere, and living organisms in the biosphere. The tutorial emphasizes the importance of understanding these spheres individually and their interactions, which affect the biosphere and the environment.

• Atmosphere

• Cryosphere

• Astrosphere

• Geosphere

What does the geosphere primarily consist of?
