Why There's a Straight Line Through Scotland

The video explains the geological history of the Great Glen Fault in Scotland, a straight fault line formed by the collision of two ancient continents, Laurentia and Gondwana, during the Caledonian orogeny. This strike-slip fault has moved horizontally several times, dissipating stress from tectonic forces. The fault's visibility increased due to glacial activity during ice ages, carving a deep valley along the fault line. The video highlights the fault's formation, characteristics, and the impact of ice ages on its current appearance.
