Liquification, Where Normally Solid Material Behaves More Like a Fluid

Liquification, where normally solid material behaves more like a fluid during an earthquake, occurs because_______ .

A) rock particles dissolve and mix with the fluids in the subsurface to become a liquid
B) friction from the vibrations melt rock and produce magmas
C) cracking in the rocks allows fluids to flow into the area and increase the amount of liquids in the subsurface
D) pore spaces between particles in unconsolidated sediments close and displace fluids
