Final answer:
Heavy rains from June to September are characteristic of the summer monsoon season in South Asia, signifying that the correct answer is d) Summer.
Step-by-step explanation:
From June to September, heavy rains sweep into the country, which is a characteristic of the summer monsoon. The monsoon is a seasonal reversal of winds accompanied by heavy rains, and during the summer, this is a key feature in South Asia's climate. The hot air over the continent rises, especially around the Thar Desert, which leads to the pulling in of moist air from surrounding bodies of water, resulting in heavy rainfall. Thus, the correct answer to the question—framed by which season heavy rains occur from June to September—is d) Summer.
The heavy rains from June to September in the described region are characteristic of the summer monsoon, making option d) Summer the correct answer. The summer monsoon is a seasonal reversal of winds that brings significant rainfall to South Asia. During this period, hot air over the continent, particularly around the Thar Desert, rises, creating a low-pressure system. This, in turn, draws in moist air from adjacent bodies of water, leading to the onset of heavy rainfall. The summer monsoon is a crucial climatic phenomenon in South Asia, contributing substantially to the region's water resources and influencing various aspects of life, agriculture, and ecosystems. Understanding the seasonal patterns, like the occurrence of heavy rains in the summer, is essential for anticipating and managing the impacts of the monsoon in this geographical area.
