Contour lines are labeled with the number on the ____.

Contour lines on a topographic map are integral for understanding the elevation and overall terrain of a landscape. These lines represent points of equal elevation, and the placement of the labels is crucial for interpreting the landscape accurately.

When contour lines are labeled with their elevation numbers, they are typically positioned on the high side or in the middle of the line. This allows anyone reading the map to easily understand the relationship between the elevation and the terrain. Knowing that the labeled number indicates the elevation of the line helps with visualizing slopes and landforms, providing essential information for landscape design, construction, and erosion control efforts.

Labeling the contour lines in this manner ensures clarity and effective communication about the topography. Misplacing the labels, such as on the low side, bottom side, or leaving them unmarked, would lead to confusion regarding the landscape's slope direction and elevation changes, making it harder to interpret the terrain accurately. Thus, labeling on the high side or in the middle provides clear guidance for anyone analyzing or working with the landscape, reinforcing its importance in landscaping and construction practices.
