"Secrets of the Earth" explores our planet with the same sense of awe and wonder normally reserved for alien worlds. Computer graphics, visual analogies and a recurring cast of expert scientists combine to reveal new aspects of the world you think you know, from canyons of gravity that warp space and time to rain triggered by cosmic rays. “Secrets of the Earth,” produced by Flight 33 Productions (“Deadliest Space Weather,” “Rocket City Rednecks”), will feature 9x 30-minute episodes.
