Earth is a complex, evolving body characterized by ceaseless change. To understand Earth on a global scale means using a scientific approach to consider how Earth's component parts and their interactions have evolved, how they function, and how they may be expected to further evolve over time. This visualization adapted from NASA helps explain why understanding Earth as an integrated system of components and processes is essential to science education. This video is available in both English and Spanish audio, along with corresponding closed captions.
