Question

Which longitudinal line passes through the center of India?
1. 82 degrees 30 minutes west longitude
2. 82 degrees 30 minutes east longitude
3. 52 degrees 30 minutes west longitude
4. 52 degrees 30 minutes east longitude

Answer 1

Correct Answer - Option 2 : 82 degrees 30 minutes east longitude

The correct answer is 82 degrees 30 minutes east longitude.

• India the mainland extends between latitudes 8°4'N and 37°6'N and longitudes 68°7'E and 97°25'E.
• 82 degrees, 30 minutes east longitude has been considered as India's Standard Meridian.
• This imaginary line passes between two poles near the Vindhya region of Mirzapur in Uttar Pradesh.
• The standard timeline of India passes through the following 5 states -
  • Uttar Pradesh
  • Chhatisgarh
  • Madhya Pradesh
  • Orissa
  • Andhra Pradesh

• In India, 82½º longitude line has been accepted as Standard Meridian for determination of Standard Time (IST) of India.
• In this way, the time on the 82½º meridian line will be considered as the time of the whole country.
• The international standard timeline 0º longitude passes through a place called Greenwich, London.
• Latitude:
  • It is the angular distance of a point on the earth’s surface, measured in degrees from the earth's center. 
  • It is a circular line that is parallel to the equator, which lies midway between the poles.
  • The latitudes are also called temperature coordinates because, with the increase in distance latitudinal distance towards the poles, the temperature reduces.
• ​Longitude:
  • ​It is an angular distance measured in degrees along the equator east or west of the prime meridian (0) degree.
