Created with Fabric.js 1.4.5 The Dust Bowl Ryan MiyaharaPeriod 5 In 1934, a big drought plus bad farming methods that led toerosion created the Dust Bowl, anecological disaster that createintense dust storms in the Great Plains. Researchers first thought the drought was caused by seasurface temperatures, but now they think it was a high pressure ridge that prevented rain. The drought covered more than 70% of western USA. And was the worst drought in over 2,005 years based on tree ring records. Grasses normally protect the soil so the storms and droughts don't cause erosion, but dry farming methods removed the grasses and created great problems. Farmers plowed the soil too much so the fine soil was too easy to blow away. Dust particles in the air also blocked the sun and that interfered with the water cycle, making the drought worse. The government helped farmers fix the "dust bowl" by limiting how many acres could be farmed and using wind control methods to protect the soil, such as planting trees and limiting cattle grazing. The government created the Soil Erosion Service which also created permanent pastures and used new practices such as crop rotation. These practices reduced blowing soil by 65%.
