What connects points of equal elevation on a topographic map?

On a topographic map, points of equal elevation are connected by contour lines. These lines represent a three-dimensional surface in a two-dimensional format, illustrating the terrain's elevation changes. Each contour line indicates a specific elevation level, and the spacing between the lines reflects the steepness of the slope; closely spaced lines indicate steep terrain while lines that are farther apart indicate a gentler slope.

Understanding contour lines is crucial for interpreting topographic maps, as they provide valuable information on the landscape's shape and gradient. This allows for visualization of hills, valleys, and other topographic features. The use of contour lines is a standard convention in cartography, making them essential tools for understanding elevation and relief in geographical analysis.
