What is a significant physical feature often shown on topographic maps?

Topographic maps are specifically designed to represent the physical features of the Earth’s surface. A key element of these maps is the portrayal of relief and elevation changes, commonly illustrated through contour lines. Mountain elevations, which indicate the height of terrain above sea level, are essential for understanding geographical landscapes. These maps help users identify features such as hills, valleys, and mountains, making them vital for activities like hiking, land use planning, and geological studies. The inclusion of mountain elevations allows for an accurate depiction of how the land varies in height, which is fundamental to the topographic representation.

In contrast, other options such as population growth trends, wildlife distributions, and economic forecasts pertain to data that do not primarily focus on the physical characteristics of the landscape. These subjects are generally addressed in social or environmental studies rather than being a key component of topographic maps, further underscoring why mountain elevations are the significant feature that defines such maps.
