Which map type uses contour lines to represent elevation changes?

A topographic map is distinctly characterized by its use of contour lines to illustrate changes in elevation across a landscape. These contour lines connect points of equal elevation, allowing users to visualize the terrain's shape, slope, and height. This representation is crucial for activities like hiking, land development, and geographical studies, as it provides a clear understanding of the physical geography of an area.

In contrast, a political map focuses on boundaries, cities, and different regions, lacking the elevation details that a topographic map offers. A climate map conveys information related to climatic conditions of an area, such as temperature and precipitation patterns, but does not include topographical details. Finally, a thematic map is designed to show specific themes or data sets, like population density or land use, rather than physical geographic features like elevation. These distinctions underline the unique purpose and functionality of topographic maps in depicting elevation through contour lines.
