Q10. What is standard Meridian on India and why?
Due to great longitudinal extent of about 29°, there can be difference of about two hours in local time of places located at two extreme points of India. As the local time changes by four minutes for every one degree of longitude, the sun rises two hours earlier in the east (Arunachal Pradesh) than in the west (Gujarat). That is why the local time of longitude of 82°30'E has been taken as the Indian Standard Time. This meridian or longitude is also termed as the Standard Meridian of India.

Q12. Explain the physical features of India.
India is marked by a diversity of physical features such as mountains, plateaus, plains, coasts and islands.
(i) In the north are the lofty snow-capped Himalayas. Him+alaya mean ‘the abode of snow’. The Himalayan Mountains are divided into three main parallel ranges.
• The northernmost is the Great Himalaya or Himadri. The world’s highest peaks are located in this range.
• Middle Himalaya or Himachal lies to the south of Himadri. Many popular hill stations are situated here.
• The Shiwalik is the southernmost range.
(ii) The Northern Indian plains lie to the south of the Himalayas. They are generally level and flat. These are formed by the alluvial deposits laid down by the rivers– the Indus, the Ganga, the Brahmaputra and their tributaries. These river plains provide fertile land for cultivation.
(iii) In the western part of India lies the Great Indian Desert. It is a dry, hot and sandy stretch of land. It has very little vegetation.
(iv) To the south of northern plains lies the Peninsular plateau. It is triangular in shape. The relief is highly uneven. This is a region with numerous hill ranges and valleys. Aravali hills, one of the oldest ranges of the world, border it on the north-west side. The rivers Narmada and Tapi flow here drain into the Arabian Sea.
(v) The Western Ghats or Sahyadris border the plateau in the west and the Eastern Ghats provide the eastern boundary. While the Western Ghats are almost continuous, the Eastern Ghats are broken and uneven (Figure 7.3). The plateau is rich in minerals like coal and iron-ore.
(vi) To the West of the Western Ghats and the East of Eastern Ghats lie the Coastal plains. The western coastal plains are very narrow. The eastern Coastal plains are much broader. There are a number of east flowing rivers. The rivers Mahanadi, Godavari, Krishna and Kaveri drain into the Bay of Bengal. These rivers have formed fertile deltas at their mouth. The Sunderban delta is formed where the Ganga and Brahmaputra flow into the Bay of Bengal.
(vii) Two groups of islands also form part of India. Lakshadweep Islands are located in the Arabian Sea. These are coral islands located off the coast of Kerala. The Andaman and the Nicobar Islands lie to the southeast of the Indian mainland in the Bay of Bengal
