Latitude and Longitude
Maps usually have a grid lines printed on them which are numbered. Normally you would use these numbers as a grid reference to indicate a location

Lines of latitude must be used with lines of longitude to help us find the absolute location. Lines of latitude alone cannot determine absolute location.
Maps can show elevation with contour lines
The method used to measure lines of longitude and latitude to determine exact location is called geodetic surveying. It involves the use of specialized instruments such as theodolites and GPS receivers to accurately measure angles and distances on the Earth's surface. These measurements are then used to calculate the precise coordinates of a particular location.
Contour Lines
It's either Latitude & Longitude or the Prime Meridian
Well, they are used for graphing information on graphs and are used on maps.
Seismic waves can be used to determine the location of an earthquake focus. These waves are triggered by tectonic plates.
A network of lines used for locating points is a coordinate grid
