Scientists know less about how one of Earth's continent came to be than about distant galaxies. But an ambitious new project called Earthscope is changing that. Using 4000 instruments spread out over millions of miles, scientists are getting their most detailed look ever about how geological forces have shaped North America. Using cutting edge graphics, we send our experts back in time billions of years and deep underground to witness first-hand the monumental events that shaped our continent, revealing for the first time the complete biography of North America.
