USA HISTORY

Detailed explanation-1: -Dust from the over-plowed and over-grazed land began to blow. By 1932 the number of dust storms had increased significantly, with 14 reported storms. This continued with 38 reported storms in 1933. In May of 1934 the great dust storms spread from the Dust Bowl area.

Detailed explanation-2: -Crops began to fail with the onset of drought in 1931, exposing the bare, over-plowed farmland. Without deep-rooted prairie grasses to hold the soil in place, it began to blow away. Eroding soil led to massive dust storms and economic devastation-especially in the Southern Plains.

Detailed explanation-3: -Dust Bowl, name for both the drought period in the Great Plains that lasted from 1930 to 1936 and the section of the Great Plains of the United States that extended over southeastern Colorado, southwestern Kansas, the panhandles of Texas and Oklahoma, and northeastern New Mexico.

Detailed explanation-4: -There were 14 large-and-awful dust storms in the region in 1932; in 1933, there were 38; all the way through 1938, the frequency and intensity of the dust storms increased with each year.

Detailed explanation-5: -In total, the Dust Bowl killed around 7, 000 people and left 2 million homeless. The heat, drought and dust storms also had a cascade effect on U.S. agriculture. Wheat production fell by 36% and maize production plummeted by 48% during the 1930s.
