How fold mountains are formed?

Fold mountains are formed through the process of continental plate tectonics. As two continental plates move towards each other, one plate will begin to slide beneath the other in a process called subduction. The subducting plate sinks deeper into the Earth's mantle, causing the overlying plate to buckle and fold. This creates mountains on the surface.

As the plates continue to collide, the folded rock layers are pushed up and become more steep, forming higher and higher mountains. The process of folding and uplift can occur over millions of years, and can be accompanied by volcanic activity, erosion, and glaciation.

Fold mountains are also formed by the collision of two oceanic plates, as the denser plate sinks beneath the other, the overlying plate is buckled to form the mountain ranges.

Fold mountains are also formed by the collision of two continental plates, as the two plates collide, the land is pushed up to form mountains.

Examples of fold mountains include the Rocky Mountains in North America, the Himalayas in Asia, the Andes in South America, and the Alps in Europe.
