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.

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 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.

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.

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 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.
