Well if u ask me i think its prime meridian but im not sure
It is the "meridian of 180° longitude", both east and west.
It is usually 180 degrees longitude, hope this helped.
The zero degrees longitude line is called the Prime Meridian. When the Prime Meridian is combined with the meridian of 180 degrees longitude, the two meridians together form a circle that divides the Earth into the Eastern and Western Hemispheres.
The opposite side of the Prime Meridian is called the 180th meridian. In a circular system of 180 degrees, the two conspire to create what scientist refer to as the great circle.
The 180 meridian crosses Vanua Levu, Rambi, and Taveuni islands in Fiji.
Longitude is the angular measurement in degrees east or west of the Prime Meridian. The Prime Meridian is at zero degrees; going east, your longitude is in degrees and minutes east, while going west your longitude is measured in degrees and minutes west. A circle is 360 degrees, so the maximum longitude is 180 degrees either way. At the 180 degree line (called the "anti-meridian") the measurement is neither east nor west.
It is usually 180 degrees longitude, hope this helped.
It's called the 180th meridian.
There are 180-meridians in the eastern hemisphere. The meridian through Greenwich, England, also called the Prime Meridian, was set at zero degrees of longitude. The meridian on the opposite side of the earth is 180-degrees.
The greatest number of degrees anyone can be from the prime meridian is 180 degrees. This is because the prime meridian itself is located at 0 degrees longitude, and the maximum longitude value is 180 degrees both east and west. Therefore, any location can be a maximum of 180 degrees away from the prime meridian.
The Eastern Hemisphere.
Longitude has a minimum of -180 (west of the prime meridian) and a maximum of 180 (east of the prime meridian). -180 and 180 are the same line, approached from opposite directions. 0 degrees of longitude runs through London, England and is called the "prime meridian."
A meridian describes an arc connecting the north and south poles (a single line of longitude). As such, a meridian will be 180 degrees.
The International Date Line
The prime meridian is a line at 0 degrees longitude.
The zero degrees longitude line is called the Prime Meridian. When the Prime Meridian is combined with the meridian of 180 degrees longitude, the two meridians together form a circle that divides the Earth into the Eastern and Western Hemispheres.
The opposite side of the Prime Meridian is called the 180th meridian. In a circular system of 180 degrees, the two conspire to create what scientist refer to as the great circle.
There are two -- the Prime Meridian -- 0 degrees, and the International Date Line -- 180 degrees.
