The Prime Meridian, which is the "zero" mark of longitude.
That would be the Equator.
an equator is an imaginary line that divides the earth from east to west
The imaginary line that divides the Earth into east and west longitude is called the Prime Meridian. It is located at 0 degrees longitude and passes through Greenwich, London, UK.
a line
The equater divides earth into 2 hemispheres (North and South). The prime meridean divides Earth into 2 other hemispheres (East and West).
The line that divides the earth into the eastern and western hemispheres is called the Prime Meridian, which runs through Greenwich, London, and has a longitude of 0 degrees.
The Equator divides the Earth by the Northern and Southern hemispheres of the Earth, while the Prime Meridian divides the Earth by the East and West Hemispheres.
The Tropic of Capricorn
The imaginary line that divides the Earth in half horizontally is called the equator. This line is situated at 0 degrees latitude and runs east-west, dividing the Earth into the Northern and Southern Hemispheres.
The Earth is divided east to west by the Prime Meridian, which runs through Greenwich, England. This imaginary line serves as the starting point for measuring longitude and divides the Earth into the Eastern Hemisphere and the Western Hemisphere.
The equator divides the earth into northern and southern hemispheres. It it a line of latitude with the value of 0 degrees.
The division between the extreme east and the extreme west is called the International Date Line.
