Detailed explanation-1: -The prime meridian separates the eastern hemisphere from the western hemisphere. Halfway around the world, at 180 degrees longitude, is the International Date Line. The prime meridian is the line of 0° longitude, the starting point for measuring distance both east and west around Earth.

Detailed explanation-2: -The prime meridian is the line drawn north to south at 0° (0 degrees) longitude. Sentences: The prime meridian divides Earth into the Eastern Hemisphere and the Western Hemisphere.

Detailed explanation-3: -Answer: The Prime Meridian divides the globe into Eastern and Western hemispheres, just as the equator divides the globe into Northern and Southern hemispheres. The Prime Meridian is at 0 degrees longitude, just as the equator is at 0 degrees latitude.

Detailed explanation-4: -Longitude is given as an angular measurement ranging from 0° at the Prime Meridian to +180° eastward and −180° westward. The Greek letter (lambda) is used to denote the location of a place on Earth east or west of the Prime Meridian.

Detailed explanation-5: -To measure longitude east or west of the Prime Meridian, there are 180 vertical longitude lines east of the Prime Meridian and 180 vertical longitude lines west of the Prime Meridian, so longitude locations are given as degrees east or degrees west.

Detailed explanation-6: -The equator is the most well known parallel. At 0 degrees latitude, it equally divides the Earth into the Northern and Southern hemispheres.
