Plot synopsis: Biologist Liz Bonnin and geologist Martin Pepper set out on a global expedition to answer the most thought-provoking questions in earth science today. Throughout history, such geologic events as volcanic eruptions, tsunamis, tectonic plate motion, earthquakes, and asteroid impacts have continually reshaped Earth's surface, spreading chaos across the planet. By performing experiments, making observations in the field, and consulting expert scientists, the eight-part series works to uncover Earth's immeasurable capacity to create and destroy.
