What is a prime meridian Class 6?
The Prime Meridian, a zero-degree longitude, divides the Earth into two equal halves—the Eastern Hemisphere and the Western Hemisphere—which contain 180 meridians each. All these meridians are equal in length and run from the North Pole to the South Pole.
What is prime meridian of India?
Ans: The longitudinal extent of India is 30o. The sun rises in the east and sets in the west. To avoid this confusion a longitude passing through the midpoint of 68o 7′ East (western most longitude) and 97o 25′ East (eastern most longitude) is taken as the standard prime meridian of India (i.e. 82o30′).

What is prime meridian and when does it established?
The prime meridian is a geographical reference line that passes through the Royal Observatory, Greenwich, in London, England. It was first established by Sir George Airy in 1851, and by 1884, over two-thirds of all ships and tonnage used it as the reference meridian on their charts and maps.
What are facts about the prime meridian?
A prime meridian is a meridian (a line of longitude) in a geographic coordinate system at which longitude is defined to be 0°. Together, a prime meridian and its anti-meridian (the 180th meridian in a 360°-system) form a great circle. This great circle divides a spheroid, e.g., Earth, into two hemispheres.
What are some characteristics of the prime meridian?
1) Each meridian is half of a great circle. 2) They run in a true north-south direction from connecting the North and South Poles. 3) They are spaced farthest apart at the equator but converges at the poles. 4) Meridians help us to determine standard time.
What countries are in the prime meridian?
The most commonly used meridian is the International Reference Meridian . There are eight nations located on the Prime Meridian: Algeria, Burkina Faso, Ghana, Mali, Spain, Togo, and the United Kingdom.
