Philippe Cousteau Jr. is no stranger to exploration. The grandson of legendary underwater explorer Jacques Cousteau, Philippe hosts and serves as executive producer of this half-hour earth science series that examines the planet. He visits diamond and gold mines to see how gems and metals are formed, travels to active volcanoes to observe what happens inside the Earth's burning core, and checks out weather stations in mountainous areas to get an idea of how weather phenomena form in the atmosphere.

Visiting places that few people get a chance to see.

Yellowstone National Park, the site of a potential supervolcano; Meteor Crater, in Arizona; powerful telescopes on Maui search the universe for meteors that might be headed Earth's way.

The Florida Everglades; Yellowstone's ecosystem; Earth as a giant ecosystem; the interdependency of all living things.

An active volcano on Hawaii; a laboratory simulates a tsunami; tsunami history and damage; whether a tsunami will happen again on the West Coast.
