A prime meridian is a meridian (a line of longitude) in a geographic coordinate system at which longitude is defined to be 0°. Together, a prime meridian and its anti-meridian (the 180th meridian in a 360°-system) form a great circle. This great circle divides a spheroid, e.g., Earth, into two hemispheres.

Hence the answer to your question would be, it is a line of longitude, connects the north and south poles and divides the western and Eastern hemisphere
