No. That would be the International Date Line.
The Prime Meridian is defined as zero longitude.
Prime meridian
The eastern hemisphere is the hemisphere that lies to the east of the Prime Meridian and ends at 180 degrees longitude while the western hemisphere lies to the west of the Prime Meridian and also ends at 180 degrees longitude. Since the Prime Meridian passes through Greenwich, UK, the vast majority of European countries lie in the eastern hemisphere. The only exceptions are Iceland, Eire, Portugal, the majority of the UK, the majority of Spain and a minority of France.
Greenwich and Paris are both east and west of the prime meridian. Greenwich, England is the location of the Prime Meridian (0° longitude), while Paris, France is located to the east of this reference line.
Countries located on the Prime Meridian include:GreenlandUnited Kingdom (England)FranceSpainAlgeriaMaliBurkino FasoTogoGhanaNote:Since the Prime Meridian is the dividing line between the eastern and westernhemispheres, any country that it crosses is in both of them.
Yes, Greenwich, a district in London, is located at 0 degrees longitude and is where the prime meridian, which establishes the starting point for the lines of longitude, passes through. However, the location of Greenwich does not lie directly on any specific latitude line.
Africa and Europe lie both east and west of the Prime Meridian.
The Philippines lie a long way to the east of the prime meridian (which passes through London).
Each of the following has territory at 100° west longitude: -- Canada -- USA -- Mexico -- Antarctica
Iceland lies mostly west of the prime meridian. The country is situated in the North Atlantic Ocean, with its westernmost point at approximately 14 degrees west longitude. However, a small part of Iceland's eastern region extends slightly east of the prime meridian. Overall, the majority of Iceland is positioned to the west.
That's going to depend on how you're holding your map or globe. -- If the north pole is at the top, then meridians to the left of the Prime Meridian mark west longitudes. -- If the south pole is at the top, then meridians to the left of the Prime one mark east longitudes. -- If the north and south poles are toward the sides of the map, then the Prime Meridian is a horizontal line between them, and there is nothing on Earth to the left or right of it.
The continents that lie mostly west of the prime meridian are North America and South America. Parts of Africa and Europe also extend into the western hemisphere, but the majority of their landmass is east of the prime meridian. Additionally, some regions in the western part of Asia and the islands of Oceania are situated west of the prime meridian.
The three countries that lie entirely west of the prime meridian are the United States, Canada, and Mexico. These countries are located on the North American continent, with their territories positioned entirely to the west of the longitudinal line that defines the prime meridian.
