A reverse fault indicates that the crust has been subjected to

  • A.pure shear only
  • B.no stress at all
  • C.compression
  • D.tension

Answer: C

Correct answer: compression

On a reverse fault the hanging wall rides up over the footwall, which shortens the crust horizontally. Shortening requires compression, so reverse faulting is characteristic of convergent settings - subduction zones and continental collisions such as the Himalaya. Normal faulting is the tensional counterpart, and strike-slip faulting the shear one.
