Faces of Earth
7.27.5
The Faces of Earth is a four-part exploration of the Earth's dynamic systems and our connection to them. The planet we live on is a complex system of elements, processes, and interactions that, over the vast expanses of geologic time, have produced the world we know today. The key to understanding Earth is that our planet has not always been like it is today, nor will it remain so in the future; in fact, the only constant on Earth is change.
