Question

Why are the world's fold mountain systems located along the margins of continents for upsc?

Answer 1

Answer:

World's fold mountains are located on the margins of the continents because fold mountains are formed from the folding of crust and uprising of the sediments accumulated by rivers along the margins of the continents by the collision of two continental plates or a continental plate and an oceanic plate.

Answer 2

Answer:

The relation between Fold Mountains and Volcanoes:

At a destructive plate boundary, the oceanic plate is subducted beneath the continental one. ... This, over millions of years, has been pushed up into huge fold mountains: The Andes. Within them, there are also volcanoes as the mountains are above the subduction zone.
