The Silent Valley National Park is located in the state of Kerala, India.
Silent Valley is located in the Nilgiri Hills and is known for its unique evergreen forests and biodiversity. It gained prominence due to a major environmental movement in the 1970s and 1980s to protect it from a proposed hydroelectric project.
It is part of the Western Ghats, a UNESCO World Heritage Site. The park is home to many endangered species, including the Lion-tailed Macaque.

The correct answer is B) Jhelum Valley.
Karewas are specific geological formations, essentially glacio-lacustrine deposits (sediments deposited in a lake formed by glacial activity), found primarily in the Kashmir Valley. The main river draining the Kashmir Valley is the Jhelum.
Karewas are flat-topped terraces known for their fertility and suitability for cultivating saffron, almonds, and other crops. They are composed of clays, silts, sands, lignite, and pebbles. These deposits provide valuable insights into the Quaternary geological and palaeoclimatic history of the region.

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.
