The correct answers are A) Droughts deprived crops of the water they needed to grow, C) Dust storms carried away fertile topsoil that crops needed to survive, and E) Droughts and dust storms deprived farmers of their primary source of income.
Droughts and dust storms added to the problems farmers faced in the 1930s in that droughts deprived crops of the water they needed to grow, dust storms carried away fertile topsoil that crops needed to survive, and droughts and dust storms deprived farmers of their primary source of income.
That difficult time in the 1930s is known as the Dust Bowl. The dirt storms were so heavy that people called "dust bowls." It was a time of drought in the plains. No rain, no water for irrigation. These affected agriculture and livestock because animals choked. Farm fields died and many people decided to move to the Western Coast in pursuit of better living conditions.
