Nappes Between Thrusts Is What Orogeny Is All Long Apron

Showcase your wry geological sense of humour with any of these gifts featuring tongue-in-cheek educational, earth scientific sayings referring to mountain building -- i.e., orogeny. Saying says it all: "Nappes Between Thursts Is What Orogeny Is All About". In geology, a nappe is a large sheetlike body of rock that has been moved more than 2 km (1.2 mi) or 5 km from its original position. Nappes form during continental plate collisions, when folds are sheared so much that they fold back over on themselves and break apart. Geologists and earth scientists will enjoy these wry suggestive plate tectonics humour gifts!
