Question

what are fold mountains​

Answer 1

Answer:

Fold mountains are formed by the effects of folding on layers within the upper part of the Earth's crust. Before the development of the theory of plate tectonics and before the internal architecture of thrust belts became well understood, the term was used to describe most mountain belts, e.g. the Himalayas.

Answer 2

Explanation:

Fold mountains are mountains formed by the folding of the Earth’s crust.

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.
