What defines a topographic map?

1. A map showing only horizontal positions of features

2. A map delineating different soils and geological features

3. A map that shows both vertical and horizontal locations of features

4. A map that represents the relative positions of boundaries of other maps

The correct answer is: A map that shows both vertical and horizontal locations of features

A topographic map is characterized by its ability to represent both the vertical and horizontal locations of features on the Earth's surface. This is achieved through the use of contour lines, which illustrate elevation changes, allowing users to visualize the terrain's shape, slopes, and relief. In addition to contour lines, topographic maps also depict various natural and man-made features such as rivers, roads, and vegetation, all laid out across a horizontal plane. This combination of vertical and horizontal information is essential for activities like hiking, engineering, and land use planning, making them valuable tools in numerous fields. The other options do not accurately capture the full definition of a topographic map. For instance, a map showing only horizontal positions neglects any vertical context, which is a crucial element of a topographic map. Similarly, a map that focuses solely on different soils and geological features would not convey the elevation changes inherent in topography. Lastly, a representation of the relative positions of boundaries of other maps does not encompass the dual nature of vertical and horizontal features that defines a topographic map.
