Explanation:

On one hand, the Great Depression is the name given to the situation that took place around 1929 due to bank runs that led to the explossion of the economic model of the United States that also affected the whole world basically.

On the other hand, a ''bank run'' is the name given, in the financial world, to the term that refers to the situation when the majority of the people of a society go the bank to withdraw their money in order to avoid losing it because of the possible bankruptcy that the bank could face.
