question 23
what type of fault involves the hanging wall moving down relative to the footwall?
normal dip - slip
thrust fault
reverse dip - slip
obtuse dip - slip

Explanation:

In a normal dip - slip fault, the hanging wall moves down relative to the footwall due to tensional forces. A thrust fault has the hanging wall moving up relative to the footwall. A reverse dip - slip fault is also characterized by the hanging wall moving up relative to the footwall. There is no such common geological term as "obtuse dip - slip" in the context of fault types.

Answer:

A. normal dip - slip
