Which map type shows the base map along with economic information?

• A. Isopach Map
• B. Thematic Map
• C. Bedrock Map
• D. Isoplets

Answer: (B)

A map that shows the base geographic context together with economic information is a thematic map. Thematic maps focus on illustrating a specific subject—like economics—across a geographic area, using the base map to provide place names, boundaries, and orientation. The economic data becomes the thematic layer, presented with colors, symbols, or shading to reveal spatial patterns such as regional differences in income or GDP, while the underlying base map remains visible to situate those patterns. Isopach maps depict the thickness of a layer such as sediment, not economic data. Bedrock maps show the geology of the underlying rocks. Isoplet (or isarithm) maps show contours of equal value for a variable, which is a general method for depicting surfaces and can be used for various themes, but the term that specifically denotes presenting a theme like economics on a geographic base is the thematic map.
