What is typically depicted in a resource map?

A resource map specifically illustrates the distribution of natural resources within a given area. These resources can include minerals, forests, water sources, agricultural land, and various other natural assets that are vital for economic development and environmental sustainability. By focusing on how and where these resources are located, a resource map serves as a crucial tool for planning, management, and utilization of the earth's resources.

In contrast to this, other types of maps serve different purposes. For example, elevation changes are depicted in topographic maps that primarily focus on terrain features rather than resource distribution. Political maps emphasize administrative boundaries and governmental jurisdictions, showcasing how regions are politically organized. Physical feature maps, while they might show landscapes and landforms, do not specifically highlight the resources available in those areas. Thus, the defining characteristic of a resource map is its emphasis on the locations and availability of natural resources, making option D the most accurate choice.
