What is 180 degrees from the prime meridian?

The antimeridian is halfway around the world, at 180 degrees. It is the basis for the International Date Line. Half of the world, the Eastern Hemisphere, is measured in degrees east of the prime meridian. The other half, the Western Hemisphere, in degrees west of the prime meridian.

How do you find the distance using the prime meridian?

As a general rule, the formula for the ​distance between meridians​ is therefore ​(2πR)(cos L)​, where L is latitude and R is the radius of the Earth.

What is the distance between meridian?

Measuring the Distance Between Meridians of Longitude Along a Parallel of Latitude. At the Equator, the distance between meridians of longitude is 60 n.m. (or 60.113 to be precise). However, as we move north or south equator, we find that the distance between them decreases as they converge towards the poles.

Why is 180 longitude considered to be an important meridian?

180 Degrees Longitude It is used to define the International Date Line. Because the Earth is spherical, traveling 180 degrees in either direction from the prime meridian will lead to 180 degrees longitude or the opposite meridian. The 180-degree meridian runs through the western Pacific Ocean.

Where is the 180 degree meridian?

The international date line, established in 1884, passes through the mid-Pacific Ocean and roughly follows a 180 degrees longitude north-south line on the Earth. It is located halfway around the world from the prime meridian — the 0 degrees longitude line in Greenwich, England.

What is the Prime Meridian Class 9?

The Prime Meridian is the imaginary line used to indicate 0∘ longitude that passes through Greenwich. It is also known as Greenwich Meridian because it passes through the place called Greenwich in London.

What is the distance between two meridian at the equator?

The distance between two consecutive meridians is equal to about 111 kilometers only at the equator.
