Question

What were the consequences of expansion of wheat cultivation in the Great Plains?

Answer 1

(i) Terrifying dust storms began to blow over the southern plains of America. Black blizzards rolled in, very often $7000$ to $8000$ feet high, rising the monstrous waves of muddy water.

(ii) They cam day after day, year after year, through the $1930s$. As the skies darkened, and the dust swept in, people were blinded and choked. Cattle were suffocated to death, their lungs choked with dust and mud.

(iii) Sand buried fences, covered field, and coated the surfaces or rives till the fish died. Dead bodies of birds and animals were scattered all over the landscape.

(iv) Tractors and machines that had ploughed the earth and harvested the wheat in the $1920s$ were now clogged with dust, damaged beyond repair.
