- The natural wonders of the world are being explained.
- 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.
- Most major geological processes require millions of year to become noticeable. Meteor impacts are exceptions which can cause comparable changes in seconds.
- The Earth isn't an ordinary generic planet. The processes that created an Earth suitable for modern are unique and surprising.
- Chile's Atacama Desert is the driest, oldest and deadest desert on earth. Yet it's plays host to living creatures and penguins even thrive nearby. It may provide clues to where to look for life on other, seemingly barren, planets.
- The relatively tiny Colorado River had substantial help in carving out a chasm as wide and deep as the Grand Canyon. The story is so complex and the evidence so scarce that it took geologist decades to unravel the mysteries.
- The Great Lakes region provided geologists with much of the evidence for the frequent ice ages that visited North America. But the lakes may be a rather transient feature of the continent dependent upon the recurring ice ages to maintain their existence.
- The Hawaiian Islands are a study in contradictions. The fastest growing islands on earth are also the fastest disappearing. Made of one of the hardest minerals, it crumbles at a touch. The world's most active volcano is nowhere near the typical volcanic regions. Geologists strive to understand these mysteries.
- The confluence of two geological forces created and continues to build the island of Iceland. They also keep the geology active with global implications. For now the massive, but retreating, glaciers are keeping the glaciers in check.
- The unique geological conditions that make Krakatoa and it's successor, Anak Krakatau, extraordinarily explosive and, despite its remoteness, dangerous are explained.
- Scotland is a ground zero for some of the most significant geologic cataclysms in Earth's history. Understanding of these titanic shifts was prompted by a mysterious lake known as Loch Ness.
- The geological history of New York City is as superlative as it's current economic impact including; a titanic mountain rage, massive volcanic eruptions, immense glaciers and an enormous flash flood.
- 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 Alps are known as the majestic mountain range of Europe. But their formation from a collision between Europe and Africa left an unstable structure that is now a classic study in erosion by rivers of water, ice and rock suggesting an even greater former glory. Left unexplained is why the Mediterranean Sea exists between the continents.
- The discovery of the Marianas trench was one of the first puzzle pieces that lead to the understanding of the most massive process that shapes the geology of the Earth; plate tectonics and the creation of new crust in the mid-ocean ridges and its subduction under the continents.
- Geologists believe the Rocky Mountains recently rose from an inland sea to twice their current size and becoming a new inland sea may be their not to distant fate.
- A tsunami is a dramatic indicator of geological activity magnifying the impact into extensive coastal destruction. Scientists searching for evidence of past tsunamis to predict when they are likely to recur and how severe they are likely to be uncover a new phenomenon, the mega-tsunami.
- Volcanologists look for patterns in the historical eruptions of Mount Vesuvius to determine when the worlds most dangerous volcano is likely to threaten the three million residents of Naples.
- The evidence, structure, history and potential threat of the Yellowstone super volcano are described.
- The dispute between John Muir and Josiah Whitney over how the Yosemite Valley formed is settled with a 200 million year long story more complex then either imagined.
- The history of discovery of gold deposits in California and Nevada and the diverse geological processes the produced the deposits are described.
- The history of Death Valley's transformation from an inland sea to a towering mountain range then to a fresh water lake and finally the salt bed we see today it revealed.
- The causes of the million year volcanic eruption in the Siberian Traps and the resulting effects that lead to the largest mass extinction in earth's history are recounted.
- The convergence of processes that resulted in the extreme height of Mt. Everest and the other Himalayan mountains is explained in conjunction with the supporting geological evidence.
