Standard Meridian is the longitude on the basis of which a countrys standard time is determined. Standard meridians all over the world are generally those longitudes which are exactly divisible by 15°. The Standard Meridian of India lies at 82° 30² E longitude and it passes through Mirzapur in Uttar Pradesh. The Indian Standard Time is five hours and thirty minutes ahead of the Greenwich Mean Time. Q4)
Why is Indian Ocean named after India?
Indian Ocean is named after India because India has the longest coastline on the ocean. It is surrounded by the ocean from three sides. The Indian Ocean serves as the major channel for Indias trade with other countries through sea route. It is the strategic importance of India on the Indian Ocean that has resulted in naming the ocean after India. Why has 82° 30² E been chosen as the Standard Meridian of India? Answer
82° 30² E has been chosen as the Standard Meridian of India because this longitude passes through the middle of the country. This balances the time gap of two hours between the westernmost and easternmost parts of India. Also, 82° 30² E is exactly divisible by 15 i.e., a difference of 30 minutes.
What is the reason for the time difference of two hours between the western most and eastern most parts of India?
There is a time lag of two hours between Gujarat in the west and Arunachal Pradesh in the east. This is because of the difference of almost 30° in terms of longitudinal coordinates between Gujarat and Arunachal Pradesh, the westernmost and the easternmost parts of the country, respectively. According to the time system, time increases from west to east by one hour with every 15°. Since Arunachal Pradesh is 30° ahead of Gujarat, there is a time gap of two hours between the two. Which Indian states share their boundaries with Pakistan? What is the effect of this? Answer
Four Indian states, namely Jammu and Kashmir, Punjab, Rajasthan and Gujarat share their boundaries with Pakistan. Owing to their boundaries with Pakistan, these Indian states are of strategic importance to India. Heavy military forces are always deployed in the border areas of these states. Safety of the people of these states is a paramount concern for the government, as India does not share a friendly relation with Pakistan. 7)

What were the main reasons that facilitated the growth of trade relations of India with the far-off lands?
Since ancient times, India has enjoyed the benefits of a favourable location in its trade relations with other countries. It is centrally located in Asia and has access to both land and sea. Since ancient times, India was well connected with countries of West Asia, Europe and China through land routes. These trade routes facilitated the exchange of goods and people on a large scale.
Also, India is surrounded by sea from three sides. This opened-up the vast possibilities of maritime trade for India with south-east Asian and African countries. Owing to these favourable conditions, India was able to amass huge wealth through its foreign trade. Describe Indias location in the world.
India is located in the northern hemisphere. It is a southward extension of Asia. India has a total area of 3.28 million square km. It is surrounded by sea from three sides. Towards its south is the Indian Ocean, to the east is the Bay of Bengal and to the west is the Arabian Sea. The geographical coordinates of India are 8° 4² N to 37° 6² N latitudes and 68°7² E to 97° 25² E longitudes. Tropic of Cancer (23° 30² N) passes midway through India.
India has two groups of islands: the Andaman and Nicobar islands in the Bay
of Bengal and the Lakshadweep islands in the Arabian Sea. Indias north is bestowed with the mighty Himalayas. It is a favourably located country in the world.
