The Prime Meridian is the meridian (line of longitude) at which the longitude is defined to be 0°.
The Prime Meridian and its opposite the 180th meridian (at 180° longitude), which the International Date Line generally follows, form a great circle that divides the Earth into the Eastern and Western Hemispheres.
The Equator is the line of latitude at which the latitude is defined to be 0°.
The Equator divides the Northern and Southern Hemispheres.
Equator
The Equator divides the Earth into the Northern Hemisphere and the Southern Hemisphere. Lines of latitude are parallel to the Equator both to the north and to the south.
The equator (0° latitude) divides the Earth into the Northern Hemisphere and the Southern Hemisphere. The Prime Meridian (0° longitude) divides the Earth into the Eastern Hemisphere and the Western Hemisphere.
The imaginary lines on the globe helps because it divides the Northern Hemisphere from Southern Hemisphere. Therefore, imaginary lines are helpful.
The two imaginary dividing lines of the hemisphere are the equator, which divides the Earth into the Northern and Southern Hemispheres, and the Prime Meridian, which divides the Earth into the Eastern and Western Hemispheres.
The Prime Meridian at 0 degrees longitude is the line on the map that divides east from west. Locations to the east of the Prime Meridian are considered in the Eastern Hemisphere, while locations to the west are in the Western Hemisphere.
The Equator divides the southern and northern hemisphere.
It is the Equator (zero Latitude) that divides the Earth into the Northern and Southern Hemispheres.
The equator divides the Earth into the Northern Hemisphere and the Southern Hemisphere.
The Equator, at 0 degrees latitude, divides the Earth into the Northern Hemisphere and the Southern Hemisphere.
The equator divides the Earth into the Northern Hemisphere and the Southern Hemisphere.
The equator divides the earth into the northern hemisphere and the southern hemisphere.
