Four effects of the Dust Bowl were: 1) People were killed, 2) Livestock were killed, 3) Crops failed, and 4) There was high levels of migration of farming families, especially to California.
Explanation:
In the 1930s, the Southern Plains suffered an extensive drought and the region became commonly referred to as the Dust Bowl. The drought led to extensive and severe dust storms throughout the area as high winds swept endless clouds of choking dust through the air stretching from Texas to Nebraska. A lot of livestock were killed and in the first year it is said that about 6,500 people died due to the fine particles of dust that affected their respiration. Crops failed across the entire region. All this happened during the Great Depression which magnified the effects and led to a sense of despair. It drove many farming away from the region as they migrated elsewhere in search of employment and better living conditions.
