← GeographyWhich geological outcome occurs when elevated carbon dioxide concentrations enhance rainfall acidity?
A)Accelerated karst topography formation✓
B)Increased soil horizon development
C)Decreased sediment deposition rates
D)Stabilized river channel morphology
💡 Explanation
Enhanced rainfall acidity causes accelerated karst topography because carbonic acid more rapidly dissolves carbonate rocks via chemical weathering, a process known as dissolution; therefore, extensive cave networks form rather than stable landscape due to slow weathering.
