- Investigates the greatest vanishing act in the history of our planet - the sudden disappearance of the dinosaurs 66 million years ago.
- Enterprise discovers a comet which contains the very rare element eisilium. Then unexpectedly a Vulcan ship arrives. Captain Vanik tells they're interested in human behavior.
- Ancient cells discovered in the arctic give rise to a carnivorous lifeform, and a cover-up.
- On the edge of the river Thames, a series of posts driven into the riverbed have been found. Also 2 Bronze Age spearheads. Are these the remains of London's first bridge or the supports of a platform where Bronze-Age people made offerings.

- Scientists, engineers, and political leaders devise a plan to save the Dead Sea, whose level has declined by more than 65 feet since 1976.
- The largest volcanic eruption of the past two million years occurred on the Indonesian island of Sumatra, 75,000 years ago. The impact from the super volcano Toba decimated the local habitat, but gas, ash and debris from Toba made their way around the planet and formed a shield in the atmosphere that deflected the sun's warming rays.
- The rocky, tree covered area is called 'The Castles' but what was it built for?
- Could the biblical story of Noah be true? 8,000 years ago, rising sea levels had global oceans surging.

- 2012–201551m8.2 (10)TV EpisodeAsia was involved in two of the greatest mass extinctions on earth. 251 million years ago the Siberian traps erupted in a massive two million year long volcanic eruption. Scientist speculate that life on land may have survived this cataclysm only because and large island, now south China, drifted apart from Gandwana. More recently India passed over a hot spot opening up the Deccan traps, another major eruption that occurred the same time the dinosaurs went extinct.
- 2012–201551m8.2 (10)TV EpisodeScientists examine geological formations of Asia to understand their impact on the people living there. The collision of India with Asia is squeezing the Tibetan Plateau between two mountain ranges and pushing China to the east creating faults leading to severe earthquakes that have cost many lives in Tibet and Sichuan Province. After breaking off from Asia Japan now sits at the collision point of three tectonic plates making it prone to volcanoes, powerful earthquakes and tsunamis. And Indonesia has a large collection of volcanoes.
- 2009– 11mTV EpisodeYou were probably taught in school that there are 92 natural elements and that plutonium is an artificial element. Not so according a a research group that found terrestrial plutonium in 1921. But plutonium is not easy to make and doesn't survive long so why is it still here? Scott explains several possibilities.
- Instead of looking at a geological feature and the convergence of mechanisms that created it, this program uses a different format; looking at one mechanism, glaciers, and the diverse effects they cause.
- The unique geological conditions that make Krakatoa and it's successor, Anak Krakatau, extraordinarily explosive and, despite its remoteness, dangerous are explained.
- Scientists present evidence that the Sahara Desert periodically transitions from desert to a lush green environment and back. They also present theories about why this happens.
- The discovery of the San Andreas Fault and efforts to understand it are described.
- The history of discovery of gold deposits in California and Nevada and the diverse geological processes the produced the deposits are described.
- What happens when the ice melts and the sea levels rise? Scientists study Antarctica in an effort to understand possible climate change through geologists looking at ancient landscapes, paleobotany, drilling, and diving.
- Uncover the sunken remains of a 4th-century basilica in Turkey. Submerged beneath the waters of Lake Iznik for hundreds of years, the church could reveal crucial insights into the early days of Christianity.
- For decades, scientists have tried to unlock the secrets of ancient DNA. Researchers struggled to find DNA in fossils that could survive millions of years. Then, one scientist had the idea to look for DNA not in fossils - but in dirt.
