they tell you where the equator, prim meridian and etc are located
The equator is one..... Hope this helped!
To find out exact location of the certain place in the earth, it needs some lines of reference i.e. latitudes & longitudes.
The point at which horizon lines receding from an observer seem to converge.
Latitude and Longitude
The Equator is the zero reference for latitude.The Prime Meridian is the zero reference for longitude.
If the contour interval is not given, find two reference (labeled) contour lines and find the number of lines between them, excluding the reference lines themselves. Then the interval can be found using the following formula: |(Difference between elevation of reference lines)| /(Number of contour lines between reference lines +1) = Contour interval For example, if you find two reference lines labeled 150m and 250m and there is one contour line between them, then |150m-250m|/(1+1)=100m/2=50m The contour interval of that map is 50 meters.
It's important to know that you reference point is moving because if an object is in motion and if it changes position it is relevant to a reference point.
If they didn't intersect, then they couldn't be called intersecting lines.

Without a fixed Point of Reference, there is nothing to be relative to.
A map reference indicating a location in terms of a series of vertical and horizontal grid lines identified by numbers or letters.
