Which type of map is used to represent broad geographic regions such as continents at a small scale?

• A. Lithofacies Map
• B. Chorographic Map
• C. Bathymetric Map
• D. Gnomonic Chart

Answer: (B)

When mapmakers want to show large areas like continents, they use a small-scale map that emphasizes general geographic relationships over fine details. A chorographic map is designed for this purpose, providing an overview of broad regions and how they sit relative to one another, without focusing on precise local features.

Other types serve different aims: lithofacies maps display rock types for geological study, not broad regional geography; bathymetric maps highlight ocean depths rather than land-wide relationships; and a gnomonic chart is a navigation projection used to plot great-circle routes, which isn’t meant for representing continents at a small scale.
