Which of the following is a characteristic of a thematic map?

A thematic map is specifically designed to present a particular theme or subject matter relative to geography, making option B the correct choice. This type of map focuses on visualizing specific data sets such as demographic information, economic indicators, or environmental factors, highlighting patterns and relationships in the identified theme across different geographic areas.

For example, a thematic map might show population density by region, allowing the viewer to quickly discern where certain populations are concentrated.

The other options do not accurately describe thematic maps. A thematic map is not intended to provide information without a specific theme, which is what the first option suggests. While thematic maps can sometimes display trends over time, they are not primarily designed to represent time series data, which relates more closely to temporal analysis than spatial analysis. Lastly, while some thematic maps can include physical characteristics of land (such as land use maps), they do not exclusively represent these features, as implied in the fourth option. The focus on specific data sets is what distinguishes a thematic map from other types of maps that might concentrate solely on physical geography.
