Which geographical line passes almost centrally through the Indian landmass, dividing it into tropical and subtropical zones?

💡 Solution & Explanation

The Tropic of Cancer at 23.5 degrees North latitude passes almost halfway through the Indian mainland, creating distinct tropical climatic conditions in the southern peninsula and subtropical conditions in the north. Unlike the Equator, which lies entirely south of India, this latitude demarcates the two thermal zones. The Tropic of Cancer passes through eight Indian states, starting from Gujarat in the west to Mizoram in the east.
