ESS2A - Earth Materials and Systems

Paul Anderson explains Earth's four spheres: geosphere, hydrosphere, atmosphere, and biosphere. He discusses energy flow, matter recycling, and interactions between these spheres. The video covers teaching strategies for different education levels and advanced topics like feedback loops and climatic changes.

Describe the process of matter recycling on Earth.

How do rocks provide clues about the Earth's changes over time?

What are feedback loops, and how do they affect the dynamics of the Earth?
