← GeographyWhich mechanism causes increased speleothem formation with increased rainfall?
A)Accelerated conduit network flow✓
B)Increased regional seismic activity
C)Decreased rates evaporite mineral deposition
D)Enhanced geothermal gradient convection
💡 Explanation
Increased rainfall causes accelerated cave conduit development because increased hydraulic pressure raises the rate of water flow through limestone fractures, enhancing dissolution, thus producing more speleothems faster, rather than other listed results.
