← GeographyWhich risk increases downwind when deforestation alters a regional albedo?
A)Reduced precipitation from decreased convection✓
B)Flash floods due to increased runoff
C)Increased CO2 absorption by new foliage
D)Higher average humidity from evapotranspiration
💡 Explanation
When albedo changes (deforestation vs forest cover), differential heating modifies temperature gradients because of regional fluxes, weakening the thermal contrast that normally drives convection and rainfall. Therefore decreased convection reduces precipitation downwind, rather than floods, CO2 absorption, or increased humidity which involve different hydrological conditions.
