What is Prime Meridian?

Question

What is Prime Meridian?

Answer 1

The Prime Meridian is the meridian (line of longitude) at which longitude is defined to be 0°

Answer 2

0 degrees longitute. It is the starting point where the time zones are measured from.

Answer 3

The Prime Meridian is the exact opposite of the equator. It goes up and down instead of side to side, and is in the "center" of the earth.

Answer 4

The Longitude are lines artificially placed, vertically, on the globe to divide the world into 360 degrees. This made map making more accurate. Along with an accurate clock mechanism for keeping time at sea made mapping possible until GPS were made.

The Prime Meridian starts at 0 degrees through the Greenwich Observatory in town of Greenwich, England, and is measured East to West.

Answer 5

the prime meridian is where longtitiude starts at 0

Answer 6

It is a line going from the North Pole to the South Pole, passing through Greenwich England.  We define this line to be 0 degrees longitude.  So, if you are at "100 degrees West", this line is what you are 100 degrees West of.

Answer 7

its the starting point for Longitude 0 degree its in Greenwich England

Answer 8

It is the 0 degree longitudinal line at greenwich in England. It is called the prime meridian as the time measured here is the prime time. ( GREENWICH MEAN TIME -- GMT)

All times measured around the world are relative to it. This gives rise to time zones. Eg the time at NEW DELHI the capital city of  INDIA is (GMT+ 5hrs 30minutes.)

Along the same longitude the time around the world is the same. For every 1 degree horizontal (latitudinal)movement the time changes by 4 minutes.   i.e to 1 degree right of the prime meridian the time is GMT + 4MINUTES.
