All of the Following Hypotheses Have Been Proposed to Explain

Multiple Choice

All of the following hypotheses have been proposed to explain intraplate earthquakes EXCEPT:

A) plate motion stresses the weakened and faulted crust at some intraplate sites.
B) mid- continent sediment deposition weighs down the crust, producing pressure that reactivates its faults.
C) substantial quantities of meltwater from the most geologically recent ice age has infiltrated and saturated networks of subsurface fractures.
D) long- term erosion has removed vast quantities of surface materials, allowing the buoyant crust to rise and generate stress on old faults.
