State whether these sentences are true or false.
The Prime Meridian is the 180-degree longitude.
A) True
B) False

Hint:
The semi-circles which connect pole to pole are called longitudes. A prime meridian is a point of longitude in the geographical coordinate system.

Complete Answer:
A prime meridian is a meridian in a geographically organized framework at which longitude is characterized to be$0^\circ $. Together, a prime meridian and its enemy of meridian form an extraordinary circle. This incredible circle separates a spheroid into two sides of the equator. In the event that one uses bearings of East and West from a characterized prime meridian, at that point they can be known as the Eastern Hemisphere and the Western Hemisphere. The longitude which runs from$0^\circ $ to $180^\circ $ the east way is called East Longitudes. The longitude which runs from $0^\circ $ to $180^\circ $ the west way is called west Longitudes. $0^\circ $and $180^\circ $ longitudes don't have course markers. The wide range of various longitudes has course markers. The prime meridian, as it passes through Greenwich, England is viewed as 0 degrees longitude.

Thus, option (B) is correct.

Additional Information:
As on the Earth, prime meridians should be discretionarily characterized. Frequently a milestone, for example, a hole is utilized; for different occasions, a prime meridian is characterized by reference to another divine article, or by attractive fields. The prime meridian of the Moon lies straightforwardly in the center of the substance of the moon, noticeable from Earth, and passes close to the pit Bruce.

Note:
Governments didn't generally concur that the Greenwich meridian is the prime meridian, making route over significant distances troublesome. Various nations distributed guides and diagrams with longitude dependent on the meridian going through their capital city.
