Which type of map focuses on a single topic or variable, like income levels?

A thematic map is designed to emphasize a specific theme or subject matter, such as population density, income levels, or the distribution of natural resources. This type of map allows viewers to visualize and analyze relationships and patterns related to that particular variable.

For instance, an income level thematic map might use varying colors or shades to represent different income brackets across regions, making it easy to identify areas of wealth or poverty at a glance. Thematic maps are particularly useful in social studies as they help convey complex information in a visual format, which can facilitate understanding of socio-economic issues.

In contrast, options like aerial maps provide a bird's-eye view of an area without focusing on a specific topic, physical maps highlight natural features such as mountains and rivers, and weather maps illustrate meteorological conditions rather than concentrating on a single theme like income levels.
