Answer:
Hi there! The effect that the Dust Bowl had on the great depression was that a lot of people's homes were ruined and since the Great depression was a point in our history where people were struggeling for money, the victims of the dust bowl did not have enough money to rebuild homes or get new things that had been ruined.
If you need another reason, it was very important that families stuck together during these times and the dust could make people sick and have to go to hospitals. Not only did people not have enough money for medical reasons, it was very hard to be away from family.
Hope this helps!
