← GeographyWhich feedback occurs as formerly vegetated surfaces are converted to loess?
A)Decreased albedo increases local temperature✓
B)Decomposition rate increases nutrient availability
C)Surface roughness captures additional sediment
D)Evapotranspiration rates hydrate topsoil structure
💡 Explanation
Decreased albedo increases local temperature by positive feedback loop because lighter soil surface reflects less solar radiation, therefore warming further accelerates soil migration of loess, rather than encouraging more vegetation as albedo stayed low.
