Geologic maps depict geologic features of a region.

• A. Topographic map
• B. Bathymetric map
• C. Geologic map
• D. Thematic map

Answer: (C)

Geologic maps are designed to show the distribution and relationships of rocks and geologic features across a region. They use colors and symbols to distinguish different rock units, faults, folds, and other structural elements, letting you see how the Earth’s history is recorded at the surface. That focus on rock types and structural geology is what makes geologic maps the best choice for depicting geologic features.

Other map types emphasize different things: a topographic map highlights the land’s surface shape and elevation with contour lines; a bathymetric map shows underwater topography and depths; a thematic map presents data about a specific theme (like climate or population) across an area. Each serves a different purpose, but only the geologic map centers on rocks and geologic structures.
