Solution
There are three different stages in the growth of mountains.

- The Orogenic stage : The tectonic forces working horizontally push and press there geosynclines to form various folds.
- Epeirogenic stage : When the whole mass of geosynclines is raised and buckled up and form a distinct series of troughs (synclines) and arcs (auticlines) i.e. Mountains and Valleys.
