They are used to locate a certain place on a map.
Latitude and Longitude
The system of latitudes and longitudes is a method used to locate points on the Earth's surface. There is a similar coordinate system used to locate objects in the sky, but it's not latitude/longitude.
Yes.
Yes.
The lines of latitude provide vertical (north-south) coordinates on a map or globe. Lines of longitude provide horizontal (east-west) coordinates. The defined geographical point is where the latitude line intersects the longitude line.
To locate any spot on the Earth's surface.
By Longitude, Latitude, minutes, seconds. Or use Google Earth.
Every point on Earth has a latitude and a longitude. No two points have the same set of two numbers.
It is like coordinates all around the earth
The Prime Meridian is a line made up of all the points on Earth that have zero longitude. There is one of those points at every possible latitude.
-- Each meridian ( 'line' ) of longitude represents all of the infinite number of points on the Earth's surface that have that one specific longitude. -- Each parallel ( 'line' ) of latitude represents all of the infinite number of points on the Earth's surface that have that one specific latitude.
No. It's the line formed by the points on Earth at zero longitude and every latitude.
