Final answer:
The Appalachians were not formed by the North American and Australian plates converging. They were created by three tectonic events involving the convergence of North American plate with parts of ancient Gondwana, not Australia.
Step-by-step explanation:
The mountain range with its origin incorrectly represented is the Appalachians: convergence of the North American and Australian plates. The Appalachian Mountains were not formed by the collision of the North American and Australian plates. Instead, they were formed during three separate tectonic events known as the Taconic, Acadian, and Alleghenian orogenies. These orogenies involved the convergence of the North American plate with various landmasses that were a part of the ancient supercontinent Gondwana, which included parts of what is now Africa and South America. Notably, the Appalachians have never been associated with the Australian plate in any of their formation stages.
The Rocky Mountains were formed by the convergence of the Farallon and North American plates during the Laramide Orogeny. Similarly, the Cascade Mountains are the result of the subduction of the Juan de Fuca plate under the North American plate, leading to volcanic activity and mountain formation. The Himalayas were created by the collision of the Indian plate with the Eurasian plate. The Alps arose from the convergence of the African plate bumping into the Eurasian plate.
Therefore, the statement that the Appalachians were formed by the convergence of the North American and Australian plates is incorrect and does not accurately represent the geological history of this mountain range.
