NOVA: Message in the Rocks

SINOPSIS

This program explores clues gathered from ancient rocks and Meteorites in an attempt to piece together how our planet formed, what happened during its earliest days, and when life first appeared. The program includes visits to the scene of a fresh fall of meteorites, several volcanic eruptions, and an underwater glimpse of molten "pillow" lava as it oozes out of volcanic vents in the sea floor.
