Question 8

Kerala experiences two distinct monsoon seasons. Which of the following statements best describes the primary reason for the exceptionally high rainfall received on the western slopes of the Western Ghats during the Southwest Monsoon, and its subsequent impact on the region's soil and agriculture?

Accepted Answer

B. Orographic uplift forces moisture-laden winds from the Arabian Sea to rise, cool, and condense, leading to heavy rainfall and the formation of laterite soils ideal for plantation crops. — The primary reason for heavy rainfall on the western slopes of the Western Ghats is orographic uplift, where moisture-laden winds from the Arabian Sea are forced to rise, cool, and condense. This heavy rainfall, combined with tropical temperatures, leads to intense leaching and the formation of laterite soils, which are highly suitable for plantation crops like rubber, tea, and spices.

Answer

A. The Coriolis effect deflects monsoon winds, causing them to condense heavily on the coastal plains, enriching alluvial soils suitable for paddy.

Answer

C. The formation of a low-pressure trough over the Bay of Bengal draws winds inland, causing widespread precipitation and the development of fertile black soils for cotton cultivation.

Answer

D. Convectional rainfall due to intense surface heating causes localized heavy showers, promoting the growth of loamy soils suitable for subsistence farming.
