INDIA - SIZE AND LOCATION - Q&A
EXERCISE
1. Choose the right answer from the four alternatives given below.
(i) The Tropic of Cancer does not pass through
(a) Rajasthan
(b) Odisha
(c) Chhattisgarh
(d) Tripura
Answer: (b) Odisha
Explanation: The Tropic of Cancer (23o30'N) passes through eight Indian states: Gujarat, Rajasthan, Madhya Pradesh, Chhattisgarh, Jharkhand, West Bengal, Tripura, and Mizoram. Looking at the map of India, Odisha lies south of the Tropic of Cancer, so it does not pass through it.
(ii) The easternmost longitude of India is
(a) 97o 25' E
(b) 68o 7' E
(c) 77o 6' E
(d) 82o 32' E
Answer: (a) 97o 25' E
Explanation: India's mainland extends between longitudes 68o7'E and 97o25'E. The value 97o25'E represents the easternmost point, located in the state of Arunachal Pradesh.
(iii) Uttarakhand, Uttar Pradesh, Bihar, West Bengal and Sikkim have common frontiers with
(a) China
(b) Bhutan
(c) Nepal
(d) Myanmar
Answer: (c) Nepal
Explanation: By observing the political map of India (Figure 1.5 in the chapter), you can see that Nepal is sandwiched between these states. Uttarakhand borders it to the west, Uttar Pradesh and Bihar to the south, West Bengal to the southeast, and Sikkim to the east.
(iv) If you intend to visit Kavaratti during your summer vacations, which one of the following Union Territories of India you will be going to
(a) Puducherry
(b) Lakshadweep
(c) Andaman and Nicobar

(v) My friend hails from a country which does not share land boundary with India. Identify the country.
(a) Bhutan
(b) Tajikistan
(c) Bangladesh
(d) Nepal
Answer: (b) Tajikistan
Explanation: India shares land boundaries with Pakistan, Afghanistan, China, Nepal, Bhutan, Myanmar, and Bangladesh. Tajikistan is located to the north of Kashmir but is separated by a narrow strip of Afghan territory (Wakhan Corridor) and does not share a direct land border with India.
2. Answer the following questions briefly.
(i) Name the group of islands lying in the Arabian Sea.
Answer: The group of islands lying in the Arabian Sea is the Lakshadweep Islands.
Explanation: India has two main island groups. The Andaman and Nicobar Islands are in the Bay of Bengal (southeast), while the Lakshadweep Islands are located in the Arabian Sea (southwest).
(ii) Name the countries which are larger than India.
Answer: The countries larger than India are Russia, Canada, USA, China, Brazil, and Australia.
Explanation: According to area (Figure 1.2 in the chapter), India is the seventh-largest country in the world. The six countries with a larger landmass are listed in descending order:
1. Russia
2. Canada
3. USA
4. China
5. Brazil
6. Australia
(iii) Which island group of India lies to its south-east?
Answer: The Andaman and Nicobar Islands lie to the south-east of India.
Explanation: Looking at the map, the Bay of Bengal is to the southeast of the mainland. This is where the Andaman and Nicobar archipelago is situated.
(iv) Which island countries are our southern neighbours?
Answer: Our southern neighbours across the sea consist of the two island countries, namely Sri Lanka and Maldives.
Explanation: Sri Lanka is separated from India by the Palk Strait and Gulf of Mannar. The Maldives are situated to the south of the Lakshadweep Islands.
3. The sun rises two hours earlier in Arunachal Pradesh as compared to Gujarat in the west but the watches show the same time. How does this happen?
Answer:
Step 1: Calculate the longitudinal difference.
The longitudinal extent of India is from Gujarat (68o7'E) to Arunachal Pradesh (97o25'E).
Difference = 97o25' - 68o7' ≈ 30o.
Step 2: Calculate the time difference.
The earth takes 4 minutes to rotate through 1 degree of longitude.
Time difference = 30o × 4 minutes = 120 minutes = 2 hours.
This means physically, sunrise is 2 hours earlier in the East.
Step 3: Explanation of Standard Time.
To avoid confusion and have a uniform time for the entire country, India has accepted the time of the Standard Meridian of India (82o30'E) as the standard time for the whole country.
Conclusion: Because the watches are set to the Standard Meridian time, they show the same time everywhere in India, regardless of the physical sunrise time.
4. The central location of India at the head of the Indian Ocean is considered of great significance. Why?
Answer: India's location is significant for the following reasons:
1. Strategic Position: India is centrally located between East and West Asia. The Trans Indian Ocean routes connecting Europe in the West and East Asia pass close by, making India a key trade hub.
2. Coastline Advantage: The Deccan Peninsula protrudes into the Indian Ocean, providing a long coastline. This helps India establish close contact with:
- West Asia, Africa, and Europe from the Western coast.
- Southeast and East Asia from the Eastern coast.
3. Dominance: No other country has such a long coastline on the Indian Ocean, justifying the ocean being named after India.

PROJECT/ACTIVITY
(i) Find out the longitudinal and latitudinal extent of your state.
Answer: (This answer varies depending on where the student lives. Below is the method to find it.)
Step 1: Open an Atlas or Google Maps.
Step 2: Locate your state on the map.
Step 3: Find the horizontal lines (Latitudes) touching the topmost and bottommost parts of your state. Note these degrees North (N).
Step 4: Find the vertical lines (Longitudes) touching the leftmost and rightmost parts of your state. Note these degrees East (E).
Example (for Delhi): Latitude: 28o24'N to 28o53'N; Longitude: 76o50'E to 77o20'E.
(ii) Collect information about the 'Silk Route'. Also find out the new developments, which are improving communication routes in the regions of high altitude.
Answer:
Silk Route Information:
- The Silk Route was an ancient network of trade routes connecting the East (China/India) and West (Europe/Rome).
- It was central to cultural interaction for centuries.
- It got its name from the lucrative trade in silk carried out along its length.
- Indian spices, textiles, and precious stones were traded for items like wool, gold, and silver.
New Developments in High Altitude Communication:
- Tunnels: Construction of strategic tunnels like the Atal Tunnel (Rohtang) to provide all-weather connectivity.
- Optical Fiber: Laying of optical fiber cables in remote Himalayan regions to provide high-speed internet.
- Satellite Phones: Use of satellite communication in areas where towers cannot be installed.
- Border Roads: The Border Roads Organisation (BRO) is building paved roads at very high altitudes to improve accessibility.
