1. Introduction to India’s Location
  • India's Location in the World:

    • India lies in the northern hemisphere.
    • Latitudinal extent: 8°4'N to 37°6'N.
    • Longitudinal extent: 68°7'E to 97°25'E.
    • The Tropic of Cancer (23°30'N) divides India into two almost equal halves.
    • The Andaman and Nicobar Islands lie to the southeast, and the Lakshadweep Islands lie to the southwest.
  • Time Zone:

    • India uses a single time zone (Indian Standard Time or IST), which is 5 hours and 30 minutes ahead of GMT (Greenwich Mean Time). The reference longitude for IST is 82°30'E, near Mirzapur, Uttar Pradesh.

2. India’s Size and Area

  • Area:

    • Total area: 3.28 million square kilometers.
    • India is the seventh-largest country in the world by land area.
    • It accounts for about 2.4% of the world’s total area.
  • Land Borders and Coastline:

    • India has a land boundary of about 15,200 kilometers.
    • It has a coastline of 7,516.6 kilometers, including the Andaman and Nicobar and Lakshadweep Islands.

3. India’s Neighbors

    • The subcontinent is characterized by geographical diversity, including mountains (Himalayas), plains (Indo-Gangetic Plains), plateaus (Deccan Plateau), deserts (Thar Desert), and coastal plains.

6. Latitudinal and Longitudinal Extent

  • Latitudinal Extent:
    • The latitudinal spread from 8°4’ N to 37°6’ N has implications on India’s climate, with tropical conditions in the southern part and subtropical to temperate conditions in the northern part.
  • Longitudinal Extent:
    • The longitudinal extent results in a time difference of about 2 hours between the easternmost and westernmost points of India.

7. Significance of India’s Location
