B) Previously cohesive sediment is caused to flow like a slurry of mud.
C) Water pressure between sediment grains removes frictional contact between them.
D) Liquefaction can cause virtual geysers of sand.
Explanation / Answer
So, option (D) is correct.
2. Resistant sandstone in the trough of a syncline would eventually form a synclinal valley.
So, option (B) is correct.
3. The Mercalli intensity scale is ineffective in providing information about all of the following earthquake effects EXCEPT determination of damage due to actual ground motion.
This intensity scale is being used for over last century to evaluate the aftereffects of Earthquake.
So, option (B) is correct.
4. The statement saying
