Answer to Question 1

When a region's average precipitation drops dramatically for an extended period of time, drought may result. The word drought refers to a period of abnormally dry weather that produces a number of negative consequences, such as crop damage or an adverse impact on a community's water supply. Drought is more than just a dry spell. Drought is not uncommon to North America. Possibly the worst weather-related disaster to hit the United States during the twentieth century was the Great Drought of the 1930s. That drought lasted a long time (late 1920s to the late 1930s) and extended over a large area. The drought, along with poor farming practices, left the topsoil of the Great Plains prone to wind erosion. As a result, wind storms lifted millions of tons of soil into the air, creating vast dust storms. Because of these infamous dust storms, the 1930s are often referred to as the Dust Bowl years.
