Final answer:
After a tornado strips the land of vegetation, the exposed bare soil becomes more susceptible to soil erosion, a process significantly exacerbated by human activities such as poor farming practices.
Step-by-step explanation:
When tornadoes pass through regions, they can strip the land down to bare soil, exposing it to the elements. As a result, this can lead to increased soil erosion. Soil erosion occurs when the protective cover of vegetation is removed, leaving the soil vulnerable to the forces of wind and water. Several historical examples illustrate the consequences of similar phenomena, such as the devastating Dust Bowl during the 1930s in the United States. Overcultivation, poor farming practices, and extreme weather conditions led to massive amounts of topsoil being blown away, creating 'black blizzards' and rendering the land infertile. The immediate increase in crop yields with the introduction of modern farming methods and pesticides during the Green Revolution initially had positive results. However, over time, these practices contributed to land degradation and soil erosion. Protecting the soil with vegetation and sustainable farming techniques is critical to preventing erosion and maintaining land productivity.
