A Student Who Had Once Lived in Alaska Describes the Following

question 27

Multiple Choice

A student who had once lived in Alaska describes the following personal experience: "The shaking of the ground beneath my house caused compaction of the particles, which caused a later mass movement resulting in my house breaking apart." Evaluate this statement.

• A) It is probably true, except that it is unlikely that the mass movement would be strong enough to break a house apart.
• B) It is probably false. Most breaking action occurs during an earthquake, not after the earthquake.
• C) The entire statement is true.
• D) It is more likely that liquefaction, caused by shaking regolith that contains water, caused the mass movement than it is likely that it was caused by compaction.
