What is the main reason behind the substantial rainfall during summer on the western coasts of India?

Correct option is A

The correct answer is (a) Western Ghats.
· The Western Ghats, also known as the Sahyadri Mountains, are a mountain range that runs parallel to the western coast of India, stretching from Gujarat in the north to Kerala in the south.
· These mountains act as a barrier to the moisture-laden winds coming from the Arabian Sea during the southwest monsoon season.
· As the moist air is forced to rise over the Western Ghats, it cools and condenses, resulting in substantial rainfall along the western coast and adjacent areas.
· This phenomenon is known as orographic rainfall, and it contributes significantly to the high rainfall received by the region during the summer monsoon season.
· The Eastern Ghats are a mountain range located on the eastern coast of India, running parallel to the Bay of Bengal.
