How The Earth Was Made

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 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.

The unique geological conditions that make Krakatoa and it's successor, Anak Krakatau, extraordinarily explosive and, despite its remoteness, dangerous are explained.

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 evidence, structure, history and potential threat of the Yellowstone super volcano are described.

Most major geological processes require millions of year to become noticeable. Meteor impacts are exceptions which can cause comparable changes in seconds.
