Detailed explanation-1: -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-2: -The 1930s was an exceptional time to be in the High Plains. The entire region, already a semi-arid climate to begin with, endured extreme drought for almost a decade. Over the 11-year span from 1930-1940, a large part of the region saw 15% to 25% less precipitation than normal.
Detailed explanation-3: -People tried to protect themselves by hanging wet sheets in front of doorways and windows to filter the dirt. They stuffed window frames with gummed tape and rags.
