Question 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 : From Gujarat to Arunachal Pradesh there is a time lag of two hours, but the watches show the same time because the time along the Standard Meridian of India (82 0 30′ E) passing through Mirzapur in Uttar Pradesh is taken as the standard time for the whole country. Because the same standard time for the whole country has been adopted, the watches show the same time in Arunachal Pradesh and Gujarat and in all parts of the country.
Question 4. The central location of India at the head of the Indian Ocean is considered of great significance. Why?
Answer : The Indian landmass has a central location between East and West Asia. India is a southward extension of the Asian continent.
The trans Indian Ocean routes which connect the countries of Europe in the West to the countries of East Asia provide a strategic central location to India.
The Deccan peninsula protrudes into the Indian Ocean, thus helping India to establish close contact with West Asia, Africa and Europe from the Western coast and South-East and East Asia from the Eastern coast.
No other country has a long coastline on the Indian Ocean as India has.
Thus, India’s eminent position in the Indian Ocean Justifies the naming of an ocean after it.

(ii) Collect information about the ‘Silk Route: Also find out the new developments which are improving communication routes in the regions of the high altitude.
Answer : (a) Do it yourself. It is given in your History book. Some information is given below
The Silk Road or Silk Route refers to a historical network of interlinking trade routes across the Afro-Eurasian landmass that connected East, South. and Western Asia with the Mediterranean and European world, as well as parts of North and East Africa.
The land routes were supplemented by sea routes, which extended from the Red Sea to coastal India, China and South-East Asia.
Extending 4,000 miles (6,500 km), the Silk Road gets its name from the lucrative Chinese silk trade along it. which began during the Han Dynasty (206 BCE – 220 CE). The central Asian sections of the trade routes were expanded around 114 BCE by the Han dynasty largely through the missions and explorations of Zhang Qian, but earlier trade routes across the continents already existed.
In the late Middle Ages. transcontinental trade over the land routes of the Silk Road declined as sea trade increased. In recent years, both the maritime and overland Silk Routes are again being used, often closely following the ancient routes.
(b) Communication routes in regions of high altitude are now-a-days through helicopter (for closer distances) and through high altitude railways like the Ouinghai railway in China linking Lhasa (capital of Tibet) with the rest of the world. More information can be found on this railway from the internet.
