Correct Option
The correct option is23°30'N
Explanation
India is located entirely in the Northern Hemisphere, extending latitudinally from 8°4'N to 37°6'N. The specific latitude that runs horizontally through the middle of the country, dividing it into distinct climatic zones, is a significant geographical reference line.
Detailed Analysis:
- 22°30'N 22°30'N: This is an incorrect latitude for the central division of India. It does not hold specific geographical significance in the context of dividing the country into equal halves.
- 23°30'N 23°30'N (Correct): This latitude is known as the Tropic of Cancer. It passes through the middle of India, dividing the country into approximately two equal halves:
- The northern part lies in the sub-tropical zone.
- The southern part lies in the tropical zone.
- It passes through eight Indian states: Gujarat, Rajasthan, Madhya Pradesh, Chhattisgarh, Jharkhand, West Bengal, Tripura, and Mizoram.
- 23°30'S 23°30'S: This latitude corresponds to the Tropic of Capricorn, which is located in the Southern Hemisphere and passes through continents such as Australia, Africa, and South America. It does not pass through India.
- 82°30'E 82°30'E: This is a longitude, not a latitude. It represents the Standard Meridian of India, which determines the Indian Standard Time (IST). It passes through Mirzapur (Uttar Pradesh).
Key Takeaway:
The Tropic of Cancer (23°30'N) is the latitude that divides India into approximately two equal halves, separating the tropical south from the subtropical north.
