← GeographyWhich landscape outcome develops when acidic rainfall percolates porous limestone?
A)Karst topography formation with extensive dissolution✓
B)Extensive glacial scouring and glacial till
C)Volcanic caldera formation with basalt flows
D)Formation of shield volcanoes erosion features
💡 Explanation
Karst topography emerges because carbonic acid increases the limestone's chemical weathering; increased rainfall facilitates dissolution. Therefore, dissolved carbonates initiate formations rather than glacial or volcanic processes, which change through disparate mechanisms.
