There are two main longitude lines. There's the one that goes through London (The Prome Meridian) and the International Date Line that crosses the Pacific Ocean. It is important to note that the Prime Meridian is at 0 degrees West/East and the Date Line is at 180 degrees West/East meaning that these two lines are on opposite sides of the world.
The equator divides the earth between the Northern Hemisphere and the Southern Hemisphere

The line of zero latitude does that. Folks often call that one the 'Equator'.
The Prime Meridian, an imaginary line running between the North and South poles of Earth, and the International Date Line, its counterpart on the opposite side of the world, both divide the Earth into its 2 halves, the Eastern and Western hemispheres. Note: The Equator divides the Earth into its other 2 hemispheric dinstinctions: the North and South hemispheres.

The region that divides North and South Korea is called the DEMILITARIZED ZONE.
Broward Boulevard is the street that divides North and South in Ft Lauderdale.
The 0-meridian, running from North to South through Greenwich, UK (near London city).
Half of any sphere is a 'hemisphere'. In the case of the equator, the halves north and south of it are called the Earth's 'northern hemisphere' and 'southern hemisphere'.
The equator is equidistant between the north and south poles.
The imaginary line that divides the Earth into eastern and western halves is the Prime Meridian, located at 0 degrees longitude. It runs from the North Pole to the South Pole and passes through Greenwich, England.
The equator divides the Earth into equal halves known as the Northern Hemisphere and the Southern Hemisphere. The equator is an imaginary line that runs horizontally around the globe and is positioned exactly halfway between the North Pole and the South Pole.
