Which risk during intense prairie wildfires increases with loess deposits?

💡 Explanation

Increased wildfires lead to the loss of vegetation, which normally stabilizes loess. Removal of the vegetative cover triggers deflation, because it reduces surface roughness available for erosion; therefore, wind erosion intensifies, rather than chemical weathering which is slow, and vegetation matters more for wildfires than infiltration differences.
