Key concepts

Extent of India and why north-south exceeds east-west

NCERT section India – Location (introduction)

Mainland limits: Kashmir (north), Kanniyakumari (south), Arunachal Pradesh (east), Gujarat (west).

Sea limits: territorial limit up to 12 nautical miles (about 21.9 km) from the coast. NCERT's conversion box: statute mile = 63,360 inches (about 1.6 km); nautical mile = 72,960 inches (about 1.8 km, 1.852 km). The southern boundary extends to 6°45'N in the Bay of Bengal.

Extent: latitude and longitude extents are each roughly 30 degrees (mainland about 8°4'N-37°6'N, about 68°7'E-97°25'E).

Distances: north to south 3,214 km; east to west only 2,933 km.

Why the difference? The distance between two parallels of latitude is the same everywhere, but the distance between two meridians decreases towards the poles. India lies north of the equator, so its 30 degrees of longitude cover fewer kilometres than its 30 degrees of latitude.

Worked example

India's latitudinal and longitudinal extents are both about 30 degrees. Why is its north-south distance (3,214 km) greater than its east-west distance (2,933 km)? (2 marks)

Try it first, then show the solutionSolution

1. The distance between two parallels of latitude stays the same everywhere.
2. The distance between two meridians shrinks towards the poles; India lies in the northern hemisphere, so each degree of longitude there is shorter than a degree of latitude.

Answer: Meridians converge towards the poles, so 30° of longitude spans fewer km than 30° of latitude.

Effects of latitudinal extent

NCERT section India – Location (introduction)

• The Tropic of Cancer passes through the middle of the country (map item).
• The southern part lies within the tropics; the northern part lies in the sub-tropical or warm temperate zone.
• This location causes large variations in landforms, climate, soil types and natural vegetation.
• The size and spread give India great physical diversity: lofty mountains in the north, large rivers (Ganga, Brahmaputra, Mahanadi, Krishna, Godavari, Kaveri), forested hills in the north-east and south, and the sandy Marusthali.

Worked example

A farmer in Kerala harvests coconuts and rice in a hot, humid climate, while an orchard owner in Himachal Pradesh grows apples with cold winters. How does India's latitudinal position help explain this contrast? (2 marks)

Try it first, then show the solutionSolution

1. The Tropic of Cancer divides India roughly into two halves: the southern part lies in the tropical zone and the northern part in the sub-tropical or warm temperate zone.
2. This spread, along with altitude, gives India a wide range of climates, so tropical crops grow in the south and temperate fruits in the northern hills.

Answer: India spans tropical and sub-tropical/warm temperate zones, giving the variety of climates and crops.

Longitudinal extent, standard meridian and IST

NCERT section India – Location (introduction)

Time difference: a longitudinal spread of nearly 30 degrees produces a time difference of nearly two hours between the easternmost and westernmost parts (the earth turns 1° in 4 minutes, so 30° × 4 = 120 minutes). The sun rises in the north-eastern states about two hours earlier than in Jaisalmer.

One time for all: yet watches in Dibrugarh, Imphal, Jaisalmer, Bhopal and Chennai show the same time, because India uses a standard meridian.

Standard meridian: countries generally choose standard meridians in multiples of 7°30' of longitude (7°30' = 30 minutes of time). India's is 82°30'E.

IST: 5 hours 30 minutes ahead of GMT (82°30' × 4 minutes = 330 minutes).

More than one zone: countries with vast east-west extent may have several standard meridians; the USA has seven time zones.

Worked example

When it is 9:00 am IST, what is the local (sun) time in Kolkata (about 88°22'E)? (2 marks)

Try it first, then show the solutionSolution

1. Difference from the standard meridian = 88°22' - 82°30' = 5°52' ≈ 5.87°; × 4 minutes ≈ 23.5 minutes.
2. Kolkata is east of 82°30'E, so its local time is ahead: about 9:23 am.

Answer: About 9:23 am local time (23.5 minutes ahead of IST).

Size, the Indian subcontinent and coastline

NCERT section Size

Size: 3.28 million sq km, 2.4 per cent of the world's land surface; the seventh largest country. (Countries larger than India in the NCERT exercise: e.g. China.)

Physical diversity: the size gives lofty mountains, large rivers, forested hills and the vast sandy Marusthali.

Indian subcontinent: bounded by the Himalayas (north), Hindukush and Sulaiman ranges (north-west), Purvachal hills (north-east) and the Indian Ocean (south). It includes Pakistan, Nepal, Bhutan, Bangladesh and India.

• The Himalayas and other ranges were a formidable barrier; only passes such as Khyber, Bolan, Shipkila, Nathula and Bomdila allowed crossing.
• This helped create a unique regional identity for the subcontinent.

Coastline: the peninsula projects into the Indian Ocean, giving 6,100 km of mainland coastline and 7,517 km in all, including the Andaman and Nicobar Islands (Bay of Bengal) and Lakshadweep (Arabian Sea).

Worked example

Kochi, Mumbai and Visakhapatnam are busy ports with fishing harbours nearby. Using India's coastline and position on the Indian Ocean, explain how this benefits the country. (2 marks)

Try it first, then show the solutionSolution

1. India has a long coastline (6,100 km for the mainland; 7,517 km with the islands), giving many sites for ports, fishing and marine resources, and territorial waters up to 12 nautical miles.
2. Its central location in the Indian Ocean, between West Asia and Africa on one side and East Asia on the other, lets ports on both coasts link India with these regions by sea.

Answer: A long coastline and central Indian Ocean position give ports, fishing, marine resources and sea links in both directions.

India and its neighbours

NCERT section India and its Neighbours

• India lies in the south-central part of Asia, bordering the Indian Ocean and its two arms, the Bay of Bengal and the Arabian Sea (Figure 1.2).
• The maritime location of peninsular India gives it links with neighbouring regions by sea and air.
• Land neighbours (from the map): Pakistan, Afghanistan, China, Nepal, Bhutan, Bangladesh and Myanmar. (NCERT's exercise asks which shares the longest land frontier; the answer expected is Bangladesh.)
• Island neighbours: Sri Lanka and the Maldives in the Indian Ocean. Sri Lanka is separated from India by the Gulf of Mannar and the Palk Strait.
• Gulf versus strait: a gulf is a large inlet of the sea into the land; a strait is a narrow channel of water joining two larger water bodies (here, the Palk Strait between the Bay of Bengal and the Gulf of Mannar side).
• Physical barriers hindered contact in the past, but modern transport and communication have largely overcome them.

Worked example

Name India's two island neighbours and the water bodies that separate India from one of them. (2 marks)

Try it first, then show the solutionSolution

1. Island neighbours: Sri Lanka and the Maldives.
2. Sri Lanka is separated from India by the Gulf of Mannar and the Palk Strait.

Answer: Sri Lanka and the Maldives; Gulf of Mannar and Palk Strait.

Where students lose marks in India – Location

The slips examiners see most often, and what to write instead.

• ✗Mistake: Giving 6°45'N as the mainland's southern limit

  Two southern figures are confused.

  Wrong working

  India's mainland extends from 6°45'N.

  Right working

  The mainland starts at about 8°4'N (Kanniyakumari); 6°45'N is the southern boundary including the islands.

  ✓Do this: Islands go further south than the mainland.

  Usually costs: 1 mark per MCQ or map item.

• ✗Mistake: Writing IST as GMT + 5 hours

  The 30 minutes are dropped.

  Wrong working

  IST is 5 hours ahead of GMT.

  Right working

  IST is 5 hours 30 minutes ahead (82°30' × 4 min).

  ✓Do this: 82.5 × 4 = 330.

  Usually costs: 1 mark.

• ✗Mistake: Explaining the distance difference by India's shape

  Students guess rather than use the earth's geometry.

  Wrong working

  India is longer north-south because it is a peninsula.

  Right working

  Meridians converge towards the poles; parallels stay equally spaced.

  ✓Do this: Think of the globe, not the map.

  Usually costs: 1-2 marks.

• ✗Mistake: Subtracting time for places east of the standard meridian

  Direction rule reversed.

  Wrong working

  97°E is behind IST.

  Right working

  Places east of 82°30'E are ahead in sun time; places west are behind.

  ✓Do this: East is early (sunrise first).

  Usually costs: 1-2 marks in a numerical.

• ✗Mistake: Drawing the standard meridian through Delhi

  Capital assumed central.

  Wrong working

  82°30'E passes through New Delhi.

  Right working

  82°30'E passes near Mirzapur, east of Delhi (Delhi is at about 77°E).

  ✓Do this: Standard meridian is in eastern-central India.

  Usually costs: 1 map mark.

   Reason (R): The figure includes the Andaman and Nicobar Islands and Lakshadweep.
   Choose (a)-(d).

   Hint

   Mainland alone is 6,100 km.

   Answer

   (a). Both true; R explains A.

4. Q4 · 2 marks · Short answerExam level

   Name five Himalayan or north-western passes mentioned in the chapter and state their historical importance. (2 marks)

   Hint

   K, B, S, N, B.

   Answer

   Khyber, Bolan, Shipkila, Nathula, Bomdila. Except for such passes, the mountains were hard to cross, so they were the routes of contact through a formidable barrier.

5. Q5 · 2 marks · Short answerHOTS / competency

   Suppose a train leaves Dibrugarh at sunrise and the same morning a train leaves Jaisalmer at sunrise. Using the chapter, roughly how far apart in IST would the two departures be, and why? (2 marks)

   Hint

   Two hours of sun time.

   Answer

   About two hours: sunrise in the north-east is nearly two hours earlier than in Jaisalmer because of the nearly 30° longitudinal spread, but both clocks show IST, so the Dibrugarh train leaves about two hours earlier by the clock.

6. Q6 · 2 marks · Short answerExam level

   What is the difference between a gulf and a strait? Give one example of each near India. (2 marks)

   Hint

   Gulf of Mannar, Palk Strait.

   Answer

   A gulf is a large inlet of the sea into the land (Gulf of Mannar); a strait is a narrow water passage joining two larger water bodies (Palk Strait).

7. Q7 · 3 marks · Short answerHarder exam level

   Imphal (about 94°E) and Jaisalmer (about 71°E) lie at nearly the same latitude. Find the difference in their local sun times, and say which sees sunrise first. (3 marks)

   Hint

   Degrees of longitude × 4 minutes.

   Answer

   Longitude difference ≈ 94° - 71° = 23°; 23 × 4 = 92 minutes, about 1 hour 32 minutes. Imphal, being further east, sees sunrise first because the earth rotates from west to east, yet both use IST.

8. Q8 · 5 marks · Long answerHOTS / competency

   How has India's location and size given it physical diversity and resources? (5 marks)

   Hint

   Latitude, size, coastline, maritime location.

   Answer

   Latitude: south in the tropics, north in the sub-tropical or warm temperate zone, giving varied climates, soils and vegetation. Size: 3.28 million sq km, seventh largest, with lofty mountains, large rivers, forested hills and Marusthali. Coastline 6,100 km (7,517 km with islands) gives marine resources and sea links. Maritime location between the Bay of Bengal and Arabian Sea connects India with neighbours by sea and air. Together these give a physically diverse land with varied resources.

9. Q9 · 2 marks · Map workHOTS / competency

   The map list asks for the southernmost point of the mainland, not of India. Explain the difference using the chapter. (2 marks)

   Hint

   Islands extend further south.

   Answer

   The mainland ends at Kanniyakumari (about 8°4'N), but India's southern boundary, including the islands in the Bay of Bengal, extends to 6°45'N; so the mainland's southernmost point is Kanniyakumari.
