The prime meridian and the International Date Line create a circle that divides the Earth into the eastern and western hemispheres. Is This Intersection Important? The Earth is widest at the equator. In 1884 the Prime Meridian was defined by the position of the large 'Transit Circle' telescope in the Observatory’s Meridian Observatory. The line starts at the north pole, passes across the Royal Observatory in Greenwich, England, and ends at the south pole. The equator divides the Northern and southern hemisphere. The Prime Meridian is located in Greenwich England. noun: our planet, the third from the Sun. Measured also in degrees, minutes, and seconds, longitude is the amount of arc created by drawing first a line from the Earth’s centre to the intersection of the Equator… All longitudes are of same importance but with the help of prime meridian(0°longitude) we can navigate whether we are going east or west.

Before this, almost every town in the world kept its own local time. According to Lilly Ponds Art Center, the equator is longer than the Earth's circumference because, unlike the circumference that is measured in a straight line, the equator traverses various topographies. This axis of the globe passes through two extreme points: known as the Poles (the North Pole and the South Pole). Set by spin axis of the Earth. It's also at this point that the Earth’s diameter is widest, believed to be around 12,756 kilometers. Why is the equator important? Unlike latitudes that have the Equator as the central Latitude, the Prime Meridian has been set as the reference point of meridians over the course of history. There are other six important latitudes, which are as follows: The North Pole marked at 90 o N ; ... Prime Meridian / Greenwich Meridian. See the fact file below for more information on the prime meridian: The Prime Meridian divides the Earth into East/West from the North Pole to the South Pole with an imaginary line along the longitude line of 0°. The Prime Meridian is the universally decided zero longitude, an imaginary north/south line which bisects the world into two and begins the universal day. The Equator separates the Northern and Southern Hemispheres. Latitude and longitude are divided into degrees (°), minutes (′) and seconds (″), with sixty minutes in a degree and sixty seconds in a minute. It is drawn exactly half way between the northern and southern hemispheres, where latitude measures 0 degrees. Some Important Longitudes include: 1. Geographers and cartographers trace imaginary horizontal and vertical lines across Earth’s surface to locate points on the globe. As the Earth’s crust is moving very slightly all the time the exact position of the Prime Meridian is now moving very slightly too, but the original reference for the prime meridian of the world remains the Airy Transit Circle in the Royal Observatory, even if the exact location of the line may move to either side of Airy’s meridian. This is similar to the way the Equator serves as the 0 latitude line and … A COVID-19 Prophecy: Did Nostradamus Have a Prediction About This Apocalyptic Year? It is also important because twice a year, during the spring and autumn equinoxes, the sun passes directly over it.

There were no national or international conventions which set how time should be measured, or when the day would begin and end, or what length an hour might be. The prime meridian is a line of geographical longitude that is defined at 0°. The Royal Observatory lies at Longitude 0° by the original definition of Airy's Transit Circle, and at Latitude is 51° 28' 38'' N. The intersection between these two invisble lines is in the middle of the Atlantic Ocean. The first parallel is the equator. The equatorial bulge also affects the ocean, creating slightly higher sea levels in equatorial regions. If you look at a world map anything east or to the right of the Prime Meridian is called East Longitude. The IRM passes 102.5 metres to the east of the historic Prime Meridian of the World at the latitude of the Airy Transit Circle here.

The decision was based on the argument that by naming Greenwich as Longitude 0º, it would be advantageous to the largest number of people. Between 1984 and 1988 an entirely new set of coordinate systems were adopted based on satellite data and other measurements and required a prime meridian that defined a plane passing through the centre of the Earth. The prime meridian, being an imaginary line, created by people to mark zero degrees longitude, could have been located anywhere. The center of the Eastern Hemisphere is located in the Indian Ocean at the intersection of the equator and the 90th meridian east, 910 km west of Indonesia in the Ninety East Ridge. Share 1. 1.
