Question :-

What is the prime meridian ?

Answer :-

• The longitude of a place is the angular distance of that place east or west of the Prime Meridian.

• On the globe, longitudes are drawn as a series of semi circles that run from North Pole to South Pole passing through the equator.

• These lines are called meridians, meaning"mid-day" as all the places on the same meridians have their noon at the same time.

• Unlike latitudes, where Equator is the only Great Circle dividing the earth into two halves, all meridians are complete circles dividing the earth into Eastern and Western Hemispheres.

• Thus, the 180° longitude (that lies just opposite to the Prime Meridian) and Prime Meridian together form one complete circle.

• The 0° longitude is called the Prime Meridian. And the 180° longitude is called the International Date Line.
