In order for a fault-block mountain to form, a must take place along a fault line and one side must be

shift, elevated

depression, dropped

shift, dropped

depression, elevated

I think the correct answer from the choices listed above is the first option. In order for a fault-block mountain to form, a shift must take place along a fault line and one side must be elevated. Fault-block mountains form when Earth's crust pushes material up and down near a fault line. Hope this answers the question.

Is it a multiple choice question? if not rhen how long does the answer need to be?
