Question 1

Kerala's rivers are characterized by their relatively short length, high gradient, and rapid flow towards the Arabian Sea. Which of the following geographical factors is the primary reason for these distinct characteristics?

Accepted Answer

B. The close proximity of the steep western slopes of the Western Ghats to the narrow coastal plain. — The primary reason for the short length and rapid flow of Kerala's rivers is its unique physiography. The Western Ghats run parallel and very close to the Arabian Sea, creating a narrow strip of land with a steep gradient. Rivers originating from the Ghats thus have short courses and descend rapidly to the sea. While high rainfall contributes to flow volume, and laterite soil might affect runoff, these are not the fundamental reasons for the rivers' inherent short length and steep profile as dictated by the topography. Dam construction alters flow but not the natural geographical characteristi

Answer

A. The extensive laterite soil cover across the state, which accelerates surface runoff.

Answer

C. High annual rainfall throughout the year, leading to constant erosion and quick drainage.

Answer

D. The presence of numerous small reservoirs and check dams that fragment river courses.
