Which term describes the map element that explains symbols and conventions?

• A. Isometric diagram
• B. Intermittent River or Lake
• C. Legend
• D. Landform Map

Answer: (C)

A map’s legend is the key that decodes symbols, colors, and line styles used on the map. It explains what each symbol represents (roads, rivers, parks, etc.) and any conventions or notes about how to read the map, so you can interpret the features correctly. Without it, the marks on the map have no defined meaning.

The other options aren’t explanatory panels: an isometric diagram is a different type of graphic representation, not the decoding guide for map symbols; an intermittent river or lake is a geographic feature; a landform map is a map type focused on terrain, not on explaining symbols.
