The high biodiversity and rainfall of the Western Ghats are linked with which physical reason?
Answer and explanation
Correct answer: A high and relatively continuous mountain wall
The governing concept is the influence of relief on monsoon rainfall and ecosystems. The Western Ghats rise close to the Arabian Sea and form a high, broadly continuous barrier. Moist south-west monsoon winds are forced to ascend the western slope, cool, and release orographic rainfall. The resulting wet forests, varied elevations, and sheltered habitats help support exceptional biodiversity, so option A is correct. A flat plain would not produce the same barrier effect. Being far from the sea would reduce the direct influence of moist maritime winds, while sand dunes indicate an arid environment and cannot explain the humid forests of the Western Ghats.
