quarrying on fold mountains

Earth Science for Kids: Mountain Geology

Fold mountains - Fold mountains are formed when two plates run into each other or collide. The force of the two plates running into each other causes the Earth's crust to crumple and fold. Many of the world's great mountain ranges are fold mountains including the Andes, Himalayas, and the Rockies.

Fold Mountains - Internet Geography

Fold mountains form when two tectonic plates collide (a compressional plate margin), this can be where two continental plates move towards each other (collision margin) or a continental and an oceanic plate converge ( destructive plate margin ). The movement of the two plates forces layers of sedimentary rock upwards into a series of folds.
