Which of the following directly contributed to soil erosion on the great plains in the 1930s?

a: railroads

b: heavy rains

c: farming

d: homesteading

The railroads helped the farmers by giving them supplies. Heavy rains would have been good, it would have replenished the dusty land. Farming was one cause, homesteading the other, since you had generations farming the land and not replenishing it, this was the main reason the Dust Bowl occured and the soil eroded.

this is not a question its simply asking you to read and write a few sentences and   the question on the bottom its fairly easy, you can do this!
