Our transcription: Although scientists sometimes disagree about the details of our planet's origins, there is little argument that Earth is unique in our Solar System. The fantastic diversity of life, the abundance of water, and our oxygen rich atmosphere are all the direct result of this planet's unusual history, a history of physical, chemical and geological evolution, as well as the evolution of life. What's especially compelling is that this process of change is not just part of Earth's past, it continues without interruption. This restless planet with its interplay of tectonic forces is as turbulent and dynamic as ever.
