The list of symbols on a map is called a legend or key.
The legend provides essential information about what each symbol on the map represents, helping users to understand the map more effectively. For instance, a blue line might indicate a river, while a green area might represent a forest. Without the legend, a map can be confusing and challenging to interpret accurately.
In essence, the legend acts as a guide, translating the visual elements of the map into meaningful data. This makes it a crucial component of map reading and comprehension.
