Question 7

Kerala's west-flowing rivers are generally short, swift, and originate from the Western Ghats. Despite this, the narrow coastal plains exhibit significant deposits of alluvial soils. Which of the following statements best explains this phenomenon?

Accepted Answer

A. High intensity of monsoon rainfall causing rapid erosion and subsequent deposition of sediments by numerous short, swift-flowing rivers onto the coastal plains. — Kerala experiences intense monsoon rainfall, leading to significant erosion in the steep Western Ghats. The numerous short, swift-flowing rivers efficiently transport these eroded sediments which are then deposited rapidly in the relatively flat and narrow coastal plains, forming alluvial soils. While major rivers contribute, the cumulative effect of many small rivers under high rainfall is the primary reason for widespread alluvial deposits.

Answer

B. The extensive floodplains of major rivers like Periyar and Pamba, which are primarily responsible for alluvial deposits across the entire coastal region.

Answer

C. Volcanic activity in the Western Ghats contributing nutrient-rich ash that mixes with river sediments, forming fertile alluvial tracts.

Answer

D. The unique tidal action in the Arabian Sea pushing back river sediments inland, thereby facilitating the formation of alluvial soils along the coast.
