Final answer:
Conventional symbols are used in maps to represent various features and have a standard meaning. In geologic maps, these symbols represent geological features like synclines, anticlines, etc.
Step-by-step explanation:
In maps, the symbols used to represent various features are called conventional symbols. These symbols are commonly used and have a standard meaning that is understood by map readers. They are included in the map legend or key to help readers interpret the information on the map.
For example, on a geologic map, conventional symbols represent different geological features such as synclines, anticlines, horizontal strata, normal faults, etc.These conventional symbols often have unique significance when used out of context and can carry strong messages in cultural and political contexts. The same applies to geologic maps where an improper understanding of the symbols may lead to misinterpretation of important data regarding the earth’s surface.
