Liquefaction Choose one: A. caused the greatest amount of damage in the San Francisco earthquake of 1908. B. does not affect clay-rich sediment, because clays stick together by cohesion. C. can cause wet, silty or sandy sediment to turn into an unstable slurry. D. is the sudden increase in strength of some soils that happens because of earthquake shaking.

Hinton · Answer 1

C. can cause wet, silty or sandy sediment to turn into an unstable slurry.

Explanation:

Liquefaction occurs whenever finely ground, water-logged silt on or around the surface of the ground weaken their strength in response to shifting of strong ground.

Liquefaction happening underneath structures as well as other buildings during earthquakes may cause serious damage.

Solid earth becomes liquid in some cases and therefore can swallow cars and roads, and even collapse structures which may sit on top of the diminishing soil.

This "liquifaction" could be the most dangerous aspect of the catastrophe.
