They represent areas on a map with a numerical value, they show regions where a difference in elevation exists, they are made of marks that connect points of equal elevation and they show the locations of roads and paths on a landscape.

Explanation:

Contour lines are a method that is used by several branches of science, like geology, cartography, meteorology, social studies, and many others, to mathematically and visually portray the location, distribution and occurrence of certain aspects in a two-dimensional way. In essence, they are lines that connect points with the same numerical value, be it in a map, or in a social studies study where the number of people at a specific location, wants to be seen. Mostly in cartography, and other earth sciences, like geology, contour lines are marks, or lines, that connect points and that allow them to know if there is an elevation, or depression in a specific terrain, and how this terrain is characterized, without having a three-dimensional or direct visual. This also allows cartographers to map different aspects of a terrain, like hills and how steep they are, the presence of water bodies and their width, extension or even depth and the same with other aspects that are present in a specific location in the map.
