Chapter 1: India - Location (ہندوستان - محل وقوع) - Detailed Notes for Exam Preparation

1. Location (محل وقوع)

• Global Position:
  • India lies entirely in the Northern Hemisphere.
  • India lies entirely in the Eastern Hemisphere.
• Latitudinal Extent:
  • The mainland of India extends between 8°4' North latitude (Kanyakumari) and 37°6' North latitude (Indira Col).
  • The southernmost point of the Indian Union is Indira Point (formerly known as Pygmalion Point) located at 6°45' North latitude in the Andaman and Nicobar Islands. (Note: Indira Point was submerged during the 2004 Tsunami but its latitudinal location remains significant).
  • The total North-South latitudinal extent is approximately 30 degrees (37°6' - 8°4' ≈ 29°). This vast extent leads to significant differences in climate and duration of day and night between the northern and southern parts.
• Longitudinal Extent:
  • India extends between 68°7' East longitude (Ghuar Moti, Gujarat) and 97°25' East longitude (Kibithu, Arunachal Pradesh).
  • The total West-East longitudinal extent is also approximately 30 degrees (97°25' - 68°7' ≈ 29°). This vast extent causes a time difference of nearly 2 hours between the easternmost and westernmost points (Earth rotates 360° in 24 hours, meaning 1° takes 4 minutes. 30° x 4 mins = 120 minutes = 2 hours).
• Key Points:
  • Northernmost Point: Indira Col (Siachen Glacier region)
  • Southernmost Point (Mainland): Kanyakumari (Cape Comorin)
  • Southernmost Point (Indian Union): Indira Point (Great Nicobar Island)
  • Westernmost Point: Ghuar Moti (Kutch, Gujarat)
  • Easternmost Point: Kibithu (Anjaw district, Arunachal Pradesh)

2. Size (رقبہ)

• Area: India's total geographical area is 3.28 million square kilometers.
• World Rank: India is the 7th largest country in the world by land area. (Countries larger than India: Russia, Canada, China, USA, Brazil, Australia).
• Percentage of World Area: India accounts for about 2.4% of the total geographical area of the world.
• Land Frontier: India has a land boundary of about 15,200 km.
• Coastline:
  • The total length of the coastline of the mainland is 6,100 km.
  • Including the Andaman and Nicobar Islands and Lakshadweep, the total coastline length is 7,516.6 km.
• Physical Boundaries:
  • India is bounded by the young fold mountains, the Himalayas, in the North, North-West, and North-East.
  • South of about 22° North latitude, India tapers and extends towards the Indian Ocean, dividing it into the Arabian Sea (West) and the Bay of Bengal (East).

3. India and the World (ہندوستان اور دنیا)

• Location: India occupies a strategic position in South Asia, located in the south-central part of the continent.
• Indian Ocean Significance:
  • India has a central location between East and West Asia.
  • The Deccan Peninsula protrudes into the Indian Ocean, giving India a long coastline and a prominent position at the head of this ocean.
  • This location facilitates trade and cultural exchange via trans-Indian Ocean routes connecting Europe and Africa with East and Southeast Asia.
  • The Suez Canal (opened in 1869) significantly reduced the distance between India and Europe by about 7,000 km.
  • India is the only country after which an ocean (Indian Ocean) has been named, highlighting its strategic importance.
• Historical Connections:
  • India's connection with the world via land routes (through mountain passes like Khyber, Bolan) is much older than maritime routes.
  • These routes facilitated the exchange of ideas (e.g., Upanishads, Ramayana, Panchatantra stories, Indian numerals, decimal system) and commodities (spices, muslin) since ancient times.
  • Architectural styles (domes, minarets from West Asia) and cultural influences (Greek sculpture) also travelled through these routes.

4. India's Neighbours (ہندوستان کے پڑوسی)

• Land Neighbours: India shares its land borders with 7 countries:
  • North-West: Pakistan, Afghanistan (shares a small border in the Pakistan-occupied Kashmir region)
  • North: China (Tibet Autonomous Region), Nepal, Bhutan
  • East: Myanmar (formerly Burma), Bangladesh
• Sea Neighbours: India has two island neighbours across the sea:
  • Sri Lanka: Separated from India by a narrow channel of sea formed by the Palk Strait and the Gulf of Mannar.
  • Maldives: Located to the south of the Lakshadweep islands in the Indian Ocean.

5. Standard Meridian of India (معیاری نصف النہار)

• Need: Due to the large longitudinal extent (~30°), the local time varies by about 2 hours between Gujarat and Arunachal Pradesh. To maintain uniform time across the country, a standard meridian is adopted.
• Longitude: The Standard Meridian of India is 82°30' East (or 82.5° E).
• Location: It passes through Mirzapur in Uttar Pradesh (near Allahabad/Prayagraj).
• Selection Rationale: It lies almost in the middle of India's longitudinal extent and is a multiple of 7°30', aligning with international conventions.
• Indian Standard Time (IST): The local time along this meridian is taken as the standard time for the whole country.
• IST and GMT: IST is 5 hours and 30 minutes ahead of Greenwich Mean Time (GMT) or Coordinated Universal Time (UTC). (IST = GMT + 5:30).

6. Tropic of Cancer (خط سرطان)

• Latitude: The Tropic of Cancer passes through India at 23°30' North (or 23.5° N) latitude.
• Significance: It divides the country into almost two equal climatic zones: the northern part lies in the sub-tropical/temperate zone, and the southern part lies in the tropical zone.
• States: The Tropic of Cancer passes through 8 Indian states (West to East):
  1. Gujarat
  2. Rajasthan
  3. Madhya Pradesh
  4. Chhattisgarh
  5. Jharkhand
  6. West Bengal
  7. Tripura
  8. Mizoram
