Which type of map might include contour lines and symbols to show elevation changes?

Topographic maps are designed specifically to represent elevation changes and the three-dimensional characteristics of the terrain in a two-dimensional format. They achieve this by using contour lines, which connect points of equal elevation and help visualize the landscape's shape and slope. By analyzing the spacing between these contour lines, you can determine steepness or flat areas of the land. In addition to elevation, topographic maps often incorporate various symbols to indicate features such as rivers, roads, trails, and buildings, providing a comprehensive view of both natural and man-made elements in a specific area.

The other types of maps listed serve different purposes. Road maps focus on navigation and transportation, highlighting roads, highways, and related infrastructure. Geographic maps provide a broader view of geographical features and distributions but do not emphasize elevation specifically. Weather maps depict atmospheric conditions and phenomena, such as temperature and precipitation patterns, rather than the physical geography of the land. Thus, topographic maps are uniquely suited for illustrating elevation through contour lines and symbols, making them the correct choice for this question.
