Question 3

During the Southwest Monsoon, Kerala experiences abundant rainfall, particularly along its coastal and midland regions. Which of the following best explains the primary role of the Western Ghats in this rainfall pattern?

Accepted Answer

B. They act as a physical barrier, forcing moisture-laden winds from the Arabian Sea to ascend, cool, and precipitate heavily on their windward side. — The Western Ghats act as a significant orographic barrier. As the moisture-laden Southwest Monsoon winds from the Arabian Sea strike these mountains, they are forced to rise, cool, and condense, resulting in heavy rainfall on the windward (western) slopes, which encompass much of Kerala's coastal and midland regions. This process is known as orographic rainfall.

Answer

A. They facilitate the inflow of dry continental winds, leading to a decrease in overall humidity and rainfall.

Answer

C. They create a rain shadow on their western slopes, causing reduced precipitation in coastal areas.

Answer

D. They channel monsoon winds directly into the eastern plains, resulting in higher rainfall in the interior districts compared to the coast.
