Appalachian Folds - Alternating beds of hard and soft Paleozoic sedimentary rocks, folded forming the hallmark of the Appalachian Valley and Ridge Province. Extending some 900 miles (1500 km) this famous belt of parallel structures reflects the several great continental collisions that formed the Appalachian chain and the Pangaea supercontinent some 300 to 400 million years ago.

Richat Structure, Mauritania - This prominent circular feature in the Sahara desert of Mauritania has attracted attention since the earliest space missions because it forms a conspicuous bull’s-eye in the otherwise rather featureless expanse of the desert. It is thought to be merely a symmetrical uplift (circular anticline or dome) that has been laid bare by erosion.
