The Prime Meridian is the meridian (line of longitude) at which longitude is defined to be 0°. The Prime Meridian and the opposite 180th meridian (at 180° longitude), which the generally follows, form a International date line great circle that divides the Earth into the Eastern and Western Hemispheres.

Unlike the parallels of latitude, which are defined by the rotational axis of the Earth (the poles being 90° and the Equator 0°), the Prime Meridian is arbitrary. By international convention, the modern Prime Meridian is one passing through Greenwich, London, United Kingdom, known as the International Meridian or Greenwich Meridian. Historically, various meridians have been used, including four different ones through Greenwich.

What is the imaginary line that divide the earth into northern and southern hemispheres?

The imaginary line is the equator, which runs east and west around the center of the globe.The equator is the imaginary line halfway between the North and South Poles and is at 0° degrees latitude. It divides the Earth into North and South Hemispheres. The Sun appears directly above the Equator at the Autumn and Spring equinox.Locations on the surface are defined by their angular distance north or south of the equator, which is latitude, and by their angular distance east or west of an arbitrary north-south line (the Prime Meridian) which is longitude.

What is located at 20 degrees west and 160 degrees east of the meridians?

The imaginary boundary between the Southern and Northern hemispheres is located at 20 degrees west and 160 degrees east of the Meridians. They are two semi-circular lines that are opposite of each other on the globe, which form an imaginary circle around the earth going through the poles.
