The process that occurs when memories that are temporarily stored in the hippocampus migrate for storage elsewhere in the brain is called memory .

Memory consolidation.

Explanation:

This is the ability of the  brain to  convert  and integrate newly  acquired  information,(synaptic consolidation) into permanent  long term  memory (system consolidation). Evidences from sleep research showed that human brain acquire memories  during the day as we interact with our immediate environment,(synaptic consolidation) and  when we sleep at night ,these memories are processed, stabilized and  integrated into existing memory to form long term memory.(system consolidation).

The conversion and integration  of  the short term memory usually begins at average of 5-10 minutes, while stabilization into long term memory which is  independent of the hippocampus  takes average of  over 1 hour after acquiring  .

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.
