How are block mountains created?

Dear Student,
Anwer to your question is as follows :

Block mountains are formed when the land between the two almost parallel faults is uplifted due to a force of tension exerted during a divergent plate movement.
As a result of this tension, the side rocks surrounding the central block go down, leaving the central block of the rock uplifted.
Examples: The Vindhayas and the Satpura ranges in India
