they tell you where the equator, prim meridian and etc are located
The equator is one..... Hope this helped!
Main reference lines typically include horizontal and vertical axes in graphs and charts, such as the x-axis and y-axis, which help in plotting data points. Additionally, reference lines like mean, median, or trend lines provide benchmarks for comparison within the data. In financial contexts, reference lines might include support and resistance levels in stock charts. These lines facilitate better visualization and interpretation of data trends and relationships.
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
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.
The Equator is the zero reference for latitude.The Prime Meridian is the zero reference for longitude.
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.
1,000 meters

If they didn't intersect, then they couldn't be called intersecting lines.
A map reference indicating a location in terms of a series of vertical and horizontal grid lines identified by numbers or letters.
