Here's why:

* Contour Lines: Topographic maps use contour lines to represent elevation. Each contour line connects points of equal elevation. The closer the lines are together, the steeper the terrain.

* Elevation Points: Topographic maps often include specific elevation points marked with numbers, giving you a precise elevation reading for that location.

* Elevation Shading: Some topographic maps use shading or color variations to indicate elevation differences, making it easier to visualize the terrain.

Other map types you might consider:

* Elevation maps: These maps use color gradients to show elevation differences.

* 3D maps: Some digital maps offer a 3D view of the terrain, allowing you to rotate and zoom in for a more detailed look at elevation.
