Question

How do lines of longitude change as they get further from the prime meridian?

Answer 1

Hint: Prime meridian is also named Greenwich meridian, as it passes through Greenwich’s royal observatory in England. A space observatory is located at Greenwich in London. The longitude that passes through Greenwich is called 0° longitude.

Complete answer:
Longitude meets at poles and they cross the equator at right angles. It is indicated that 10 degree E and 10 degree W of the Greenwich meridian because the Greenwich meridian is considered as central longitude. ‘W’ stands for places west of the Greenwich meridian and ‘E’ stands for the places east of the Greenwich meridian.
To have a clear description of a certain area or part of Earth’s surface, Longitude and latitude help. Longitudes are the imaginary line that is marked from the north to south direction.
Earth revolves around the sun in the west to the east direction, during that revolution, lines of longitude move from the prime meridian that’s why the sun rises in the east and sets in the west direction. Prime meridian divides the world map into half and when the lines of longitude move away from prime meridian day and night occurs.
The prime meridian dividing the world map, in that east side of the prime meridian is called eastern hemisphere and west side of the meridian is called a western hemisphere.

Note: Thus lines of longitude change as the Earth revolves from west to east direction from the prime meridian. When the lines of longitude change as they far from the prime meridian there would be a change in day and night.
