Quizplus · Accepted Answer

The Appalachians formed as a result of the Alleghany orogeny, which occurred during the Late Paleozoic era (between about 325 and 260 million years ago). This orogeny was caused by the collision of the ancient continents of Laurentia (which included present-day North America) and Gondwana (which included parts of present-day Africa, South America, Australia, and Antarctica). The collision caused the sedimentary and volcanic rocks that had accumulated on the continental shelf to be squeezed and folded, forming the Appalachian Mountains.
