FORMATION OF FOLD MOUNTAINS Fold mountains are large mountain ranges formed mainly by the bending and folding of the Earth’s crust due to compressional forces. These forces occur when two tectonic plates collide or move toward each other. PROCESS OF FORMATION 1. PLATE COLLISION: Fold mountains usually form at convergent plate boundaries, where two continental plates (or sometimes an oceanic and a continental plate) collide. The immense pressure causes the crustal rocks at the edges of the plates

Mountains form where two continental plates collide. Since both plates have a similar thickness and weight, neither one will sink under the other. Instead, they crumple and fold until the rocks are forced up to form a mountain range. As the plates continue to collide, mountains will get taller and taller | Science Of The Universe
