By a fortuitous accident of mnemonic convenience,
it's called the "Eastern Hemisphere".
The Prime Meridian and the meridian of 180° longitude, together, do.
It is known as the Eastern Hemisphere, with lines of longitude easterly from the Prime Meridian (zero longitude) to the Datum Line of 180 degrees longitude. In the opposite direction from the Prime Meridian is the Western Hemisphere. To the north of the Equator is the Northern Hemisphere, and to the south of the Equator is the Southern Hemisphere.
Yes. Every meridian of longitude does that.
the answer is southern hemisphere
The prime meridian separates the Eastern Hemisphere from the Western Hemisphere on Earth. It is the line of longitude designated as 0°, from which all other lines of longitude are measured.
The distance east or west of the prime meridian?
it is in the middle of the earth longitude(east and west)
Technically, they all do, but the prime meridian is the one that's recognized.
Prime Meridian
The eastern hemisphere is the part of the earth that is east of the prime meridian and west of 180 degrees longitude.
The Prime Meridian, which is 0 degress longitude.
Longitude lines in the eastern hemisphere are labeled with an E for east, indicating their position relative to the Prime Meridian. The Prime Meridian, located at 0 degrees longitude, serves as the starting point for measuring eastward and westward distances on the globe.
