What is the longitude of the prime meridian?

How do lines of longitude differ from lines of latitude?

What is longitude of the prime meridian?

What is the line of longitude for a place that is west of the prime meridian halfway between the prime meridian and the 180 line of longitude?

International Date Line
The meridian that runs through Greenwich, England, is internationally accepted as the line of 0 degrees longitude, or prime meridian. The antimeridian is halfway around the world, at 180 degrees. It is the basis for the International Date Line.

Is the prime meridian the standard for longitude?

Just as the prime meridian is the standard for longitude, UTC is the standard for time. All countries and regions measure their time zones according to UTC. There are 24 time zone s in the world.

Which is the halfway point from the prime meridian?

The Earth’s longitude measures 360, so the halfway point from the prime meridian is the 180 longitude line. The meridian at 180 longitude is commonly known as the International Date Line.

Is the prime meridian the International Date Line?

The meridian at 180 longitude is commonly known as the International Date Line. As you pass the International Date Line, you either add a day (going west) or subtract a day (going east.) The prime meridian and the International Date Line create a circle that divides the Earth into the eastern and western hemispheres.

Is the Western Hemisphere west of the prime meridian?

The western hemisphere is west of the prime meridian and east of the International Date Line. The Americas, the western part of the British Isles (including Ireland and Wales), and the northwestern part of Africa are landmasses in the western hemisphere.
