Earth Systems and Their Interactions

The video introduces Earth Systems science, highlighting its integration of various scientific disciplines. It explains how NASA uses technology and data from satellites to study Earth's systems, including the geosphere, atmosphere, hydrosphere, and biosphere. The video discusses the interactions between these spheres and their impacts on climate and human activities. It emphasizes NASA's role in understanding these complex interactions from space and the economic importance of studying Earth systems. The video concludes with a call to action for viewers to understand and manage Earth's systems responsibly.
