The prime meridian is the imaginary line that divides Earth into two equal parts: the Eastern Hemisphere and the Western Hemisphere. The prime meridian is also used as the basis for the world's time zones. The prime meridian appears on maps and globes. It is the starting point for the measuring system called longitude.Any line of longitude (a meridian) can serve as the 0° longitude line. However, there is an international agreement that the meridian that runs through Greenwich, England, is considered the official prime meridian.A meridian is a north-south line, selected as the zero reference line for astronomical observations. By comparing thousands of observations taken from the same meridian it's possible to build up an accurate map of the sky.
Why was prime meridian created : But there is no fixed position, east-west, or no fixed longitude. And very soon people realized that they did need a zero longitude from which to make all their measurements. So, in 1884, a commission of all the countries in the world got together and voted to make Greenwich the prime meridian of the world.
Why is Greenwich Mean Time 0
The recommendation was based on the argument that naming Greenwich as Longitude 0º would be of advantage to the largest number of people. As the reference for GMT, the Prime Meridian at Greenwich therefore became the centre of world time and the basis for the global system of time zones.
What is the difference between the Equator and the prime meridian : The main distinction between the Equator and the Prime Meridian is that the Equator is a line that circles the Earth halfway between the North and South poles, whereas the Prime Meridian runs through Greenwich, England. The Equator is the imaginary line that circles the globe in the middle.
The equator is significant because it divides the Earth into the Northern and Southern hemispheres. The equator is also important for navigation. This line sits at 0° latitude, making it the reference point when travelers, map-makers, or anyone else needs to determine the latitudinal location of an object on Earth. Three facts about meridians are:
They are also called lines of longitude.
They run in a north-south direction from the North Pole to the South Pole.
They measure the distance in degrees east or west of the prime meridian, which is the reference point for time zones.
What are some facts about the meridian
In astronomy, the meridian is the great circle passing through the celestial poles, as well as the zenith and nadir of an observer's location. Consequently, it contains also the north and south points on the horizon, and it is perpendicular to the celestial equator and horizon.The recommendation was based on the argument that naming Greenwich as Longitude 0º would be of advantage to the largest number of people. As the reference for GMT, the Prime Meridian at Greenwich therefore became the centre of world time and the basis for the global system of time zones.How does prime meridian effect the time around the world – Quora. It defines Universal Time (GMT) and serves as a reference for coordinated global time. Time zones are based on its 15-degree increments, advancing one hour per zone to the east and setting back one hour per zone to the west. The hour difference is because in the UK during summer the UK uses British Summer Time (BST) which is Greenwich Mean Time (GMT) plus one hour. That time change/difference is only apparent in the period April to October after which London and the UK reverts to GMT for the remainder of the year.
Was time invented in Greenwich : Greenwich Mean Time is the yearly average (or 'mean') of the time each day when the sun crosses the Prime Meridian at the Royal Observatory in Greenwich, London. Astronomer Royal John Flamsteed developed the concept of Greenwich Mean Time in the 17th century.
Which country is closest to the equator : Answer: There are a total of 13 countries that pass through the equator line – Ecuador, Colombia, Brazil, Congo, Kenya, Somalia, Indonesia, Kiribati, Maldives, Malaysia, Thailand and Vietnam. Of these, Ecuador, Kenya and Somalia are the only countries that lie completely on the equator line.
Do the equator and the Prime Meridian meet
Null Island is the location at zero degrees latitude and zero degrees longitude ( 0°N 0°E), i.e., where the prime meridian and the equator intersect. Answer: There are a total of 13 countries that pass through the equator line – Ecuador, Colombia, Brazil, Congo, Kenya, Somalia, Indonesia, Kiribati, Maldives, Malaysia, Thailand and Vietnam. Of these, Ecuador, Kenya and Somalia are the only countries that lie completely on the equator line.What would happen if someone stood still at the equator of a spinning planet like Earth People do it all the time. Nothing noticeable happens even though their circling the earth's axis at about 1000 miles an hour, faster than those at higher or lower latitudes.
What are two facts about meridians : The position of a point along the meridian is given by that longitude and its latitude, measured in angular degrees north or south of the Equator. On a Mercator projection or on a Gall-Peters projection, each meridian is perpendicular to all circles of latitude. A meridian is half of a great circle on Earth's surface.
