Question

The International Date Line is approximately equal to____
a) The equator
b) 180th meridian
c) 100th meridian
d) None of the above

Answer 1

Hint: Latitude means the geographical coordinates, north-south of the equator that determine the distance of a point. Longitude refers to the geographical coordinate, which describes the distance of a point east-west of the Prime Meridian. The concept of latitude is the measurement of a portion of the Planet in relation to the equator of the Earth's north or south or the amount of freedom granted to anyone to deviate from a standard pattern of thinking or action.

Complete Answer:
- Founded in 1884, the International Date Line travels through the mid-Pacific Ocean and approximately parallels the Earth's north-south line of 180 degrees longitude. From the prime meridian, the zero degree longitude formed in Greenwich, England in 1852, it is located halfway around the world.
- At approximately 180 degrees longitude, The International Date Line is an imaginary line that distinguishes one day from the next, situated halfway around the globe. When you cross the International Date Line, the date changes.
- You subtract a day while crossing the International Date Line from west to east, and you add a day if you cross the line from east to west. The time difference on either side of the line is not necessarily 24 hours, depending upon which time zone the nation follows.

Hence, the correct answer is option b).

Note: Throughout the nation and all its territories, the Republic of India uses only one time zone, called Indian Standard Time (IST), which is equivalent to UTC+05:30, i.e. five and a half hours ahead of Synchronized Universal Time (UTC). India does not actually observe daylight saving time (DST or summer time).
