importance of equator and prime meridian

-The purpose of the prime meridian is to specify a second coordinate to indicate distance east or west from an agreed-upon reference line-The prime and other meridians are devised by nature-The prime meridian is recognized as an imaginary line passing through the Royal observatory at Greenwich, England 2. what is the importance of the equator and prime meridian? The line itself divided the eastern and western hemispheres of the Earth - just as the Equator divides the northern and southern hemispheres. Both the equator and the prime meridians are symbols used in maps. Secondly, why is the prime meridian and equator important? Share 1. noun: area of the Earth east of the prime meridian and west of the International Date Line. It's an imaginary line that divides the Earth into two equal halves, and it forms the halfway point between the South Pole and the North Pole at 0 degrees latitude, according to National Geographic. 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… Circles of Latitude are called parallels while half of a longitudinal circle is called a Meridian. In other words, the equator is at 0° latitude. 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 Earth is the only place in the known universe that supports life. Share 1. The decision was based on the argument that by naming Greenwich as Longitude 0º, it would be advantageous to the largest number of people. It marks the line above which the sun is directly overhead on the March and September equinoxes. Secondly, why is the prime meridian and equator important? It's understood that the total distance around the Earth at the equator is believed to be 40,075 kilometers. The prime meridian, on the other hand, is an imaginary line, created by people to mark zero degrees longitude. It marks the line above which the sun is directly overhead on the March and September equinoxes. How is the equator similar to the prime meridian? C) Prime Meridian Agreed "zero point" for measuring a position around the Earth along the Equator. The most important line of latitude is the equator, which runs horizontally around the fattest part of the earth. This circle and telescope were originally proposed by the seventh Astronomer... What is the Prime Meridian and why is it in Greenwich? The second was that in the late 19th century, 72% of the world's commerce depended on sea-charts which used Greenwich as the Prime Meridian. Before this, almost every town in the world kept its own local time. The equator is the zero degrees latitude while the prime meridian is the zero degrees longitude. The axis is shown in the form of a needle on the globe. The Royal Observatory in Greenwich is where east meets west at Longitude 0°. The Equator and Prime Meridian are circles that stretch all the way around the Earth. Share with your friends. The prime meridian is the vertical line that marks the zero degree longitude measurement on the globe of Earth and intersects the latitude lines, which are horizontal. Prime Meridian or Greenwich Meridian is the 0 o longitude which passes through the Royal Observatory at Greenwich, near London. longitude by international agreement.
