Exploring Earth's Four Spheres and Their Interactions

The video introduces the four spheres of Earth: geosphere, atmosphere, hydrosphere, and biosphere. It explains their components and how they interact to shape the natural world. The geosphere includes Earth's solid layers, the atmosphere consists of gases, the hydrosphere encompasses all water forms, and the biosphere contains all living organisms. The video also explores interactions between these spheres, such as water shaping land through erosion, volcanic activity affecting the atmosphere, and the role of living organisms in enriching soil.

Which of the following is NOT one of the four spheres discussed in the video?

• Atmosphere

• Lithosphere

• Hydrosphere
