Cierra is taking a test in geography and is trying to recall the capital of turkmenistan. in answering this question, cierra is largely relying on her: semantic memory episodic memory prospective memory procedural memory

The answer is semantic memory.

Explanation:

Semantic memory contains a portion of long-term memory through which ideas and concepts are processed. These ideas and concepts are not related to personal experience. Semantic memory refers to things that belong to common knowledge like the names of colors, the countries' capitals as well as some other basic facts that we have obtained throughout our lives.

The term was established in 1972 when there was a collaboration between Endel Tulving who represented the University of Toronto and Wayne Donaldson who represented the University of New Brunswick when they were investigating the impact that the organization had in human memory.
