Statement 3 is correct because the Narmada river flows through a classic example of a rift valley, which is a graben structure formed by faulting between the Vindhyan and Satpura ranges. Statement 1 is debatable; while the Kullu Valley is a structural valley shaped by tectonic forces, calling it purely a “strike valley” might not be the most precise geological classification. Statement 2 is incorrect; the Kangra Valley is a longitudinal valley running parallel to the Dhauladhar range, not a transverse valley which cuts across ranges.
– Narmada River flows through a well-known rift valley in India.
– Kullu Valley is primarily a structural valley influenced by faulting.
– Kangra Valley is a longitudinal valley, parallel to the Dhauladhar range.
A rift valley is a linear shaped lowland between several highlands or mountain ranges created by the action of a geologic rift or fault. Strike valleys are typically formed by erosion along the strike of weak rock layers in folded or tilted strata. Transverse valleys cut across geological structures like mountain ranges.
