Because there are many parallel folds and troughs, folding results in the formation of long chains of parallel mountain ranges having high peaks. The Himalayas, Alps, Rockies, and Appalachians are famous fold mountains. Rift valleys and block mountains are two main landforms formed due to faulting. The distribution of Folded and Faulted Landforms are discussed below
Distribution of Folded and Faulted Landforms
The fold mountain system arranged in long lines is found almost in every continent. Most of them are interlinked arcs extending through oceans. The Alpine Himalayan system is one such example that stretches between Africa, Arabia, and India in the south and Europe and Asia in the north.
The Circum Pacific Belt comprises the Andes, the North American Cordillera, and Island arcs. These two systems of fold mountains meet in Australia.
Block mountains along with rift valleys are also found throughout the world. Sierra Nevada Mountains in California, USA, are one of the major mountain systems in the world. Because rift valleys are caused by the weakness of the crust, earthquakes and volcanoes are generally associated with these landforms.
