Given below are two statements. 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
Explanation
Statement 1 is false, because most hazardous landslides are triggered by rainfall and water saturation, not earthquakes.
Statement 2 is true, as landslides involve earth material moving when shear stress overcomes shear strength.
Heavy or prolonged rain adds weight and reduces friction, setting off most slope failures.
Earthquakes do trigger some landslides but account for a smaller share overall.
Slopes fail once the driving stress exceeds the resisting strength of the material.
Deforestation and steep slope construction further raise the risk of landslides.
