Topographic maps show slope: 

Landforms and man-made structures are the reason cartographers have developed topographic maps. Scientists need models that not only display the shape and size of a landform, but also display the elevation of a landform or structure. Topography focuses on the sizes, shapes, and elevations of landforms within a specific area. Similar for other types of maps, cartographers use information compiled in field surveys and from aerial pictures to design topographic maps. Scientists developed these maps which show natural land forms (mountains, rivers, hills, etc.) and human-made land forms (buildings, dams, roads, etc.). Topographic maps show slope Monday

How contour lines work: 

How contour lines work Contour intervals reflect changes in the land. These intervals are measurements that refer to the difference between the elevations of two neighboring contour lines. Contour intervals are always the same throughout the same map; however, they can be different from map to map. Tuesday

Contour Lines, cont.: 

When contour lines have a huge amount of space between them, then the change in the area's elevation is gradual. This also means that the area is considered to be level. When there is very little space between the contour lines, then there is a sharp increase in the area's elevation. You usually see lines like this at the base of mountains right before the land becomes very steep . Contour Lines, cont.
