← GeographyWhich atmospheric phenomenon is intensified from the Foehn effect, leading to increased wildfire risk?
A)Accelerated vegetation decomposition rates
B)Reduced atmospheric nitrogen fixation
C)Increased surface air aridity✓
D)Enhanced cloud condensation nuclei formation
💡 Explanation
When air descends on the leeward side of a mountain range due to the Foehn effect, adiabatic compression occurs, because the air warms and its relative humidity decreases, leading to increased surface air aridity, drying out vegetation. Therefore surface air aridity intensifies, increasing wildfire risk, rather than decomposition, nitrogen fixation, or cloud seeding, which relate to different environmental mechanisms.
