Given below are two statements. Statement I: Most of the hazardous landslides are induced by earthquakes. Statement II: All landslides involve the falling of earth material under shear stress. In the light of the above statements, choose the correct answer from the options given below.
- Statement I: Most of the hazardous landslides are induced by earthquakes.
- Statement II: All landslides involve the falling of earth material under shear stress.
ABoth Statement I and Statement II are true
BBoth Statement I and Statement II are false
CStatement I is true but Statement II is false
DStatement I is false but Statement II is true ✓ Correct
Correct answer: (D) Statement I is false but Statement II is true — Statement I is false and Statement II is true, so the answer is Statement I is false but Statement II is true.
Explanation
★Statement I is false and Statement II is true, so the answer is Statement I is false but Statement II is true.
★Landslides have many causes, such as heavy rain, slope instability and human activity.
★Earthquakes are only one of several causes, not the source of most hazardous landslides.
★So the claim that most are induced by earthquakes is false, making statement I false.
★Every landslide is a downslope movement of rock, debris or earth.
★This movement occurs when shear stress overcomes the material's strength.
★So statement II is true, and statement I is false.
