Which of the following is a problem caused by accelerated erosion?

Accelerated erosion is a significant environmental concern that leads to various issues, one of which is increased imperviousness. When erosion occurs at an accelerated rate, it can lead to the removal of topsoil and other materials that usually would provide coverage and allow for the absorption of water. This loss contributes to a higher prevalence of surfaces like concrete and asphalt in urban areas, which do not allow for water infiltration. As a result, these surfaces contribute to increased runoff, which can lead to flooding and further erosion issues in nearby areas.

The other options present outcomes that are typically not associated with accelerated erosion. Improved habitat for wildlife and enhanced stormwater management are generally outcomes of effective land management practices that promote soil retention and proper drainage. Additionally, greater agricultural productivity is usually linked to healthy soil and effective erosion control measures; accelerated erosion diminishes soil quality and can lead to reduced crop yields. Consequently, increased imperviousness directly reflects a problem exacerbated by accelerated erosion, reinforcing the negative impacts it has on the landscape and ecosystem.
