Question
1. At what types of boundary do mid-ocean ridges occur? (Select all that apply.)
A. Convergent boundary
B. Divergent boundary
C. Transform boundary
2. True or False? Compressional forces cause normal faulting.
3. When the hanging wall block moves up relative to the footwall block it is called a _________.
A. Normal Fault
B. Reverse Fault
C. Strike-Slip Fault
4. When the footwall block moves up relative to the hanging wall block it is called a _________.
A. Normal Fault
B. Reverse Fault
C. Strike-Slip Fault
5. What method do scientists use to locate the epicenter of an earthquake?
Explanation / Answer
1. divergent boundary. ( mid-ocean ridges occur when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary).
2. False (Compressional forces push the hanging wall upward relative to the footwall, producing a reverse fault which are reverse of normal faults)
3. reverse fault (When the hanging wall block moves up relative to the footwall block, the dip-slip fault is classified as a reverse fault ).
4. Normal fault (When the hanging wall block moves down relative to the footwall block, the dip-slip fault is classified as a normal fault).
