← GeographyWhich outcome occurs when excessive irrigation causes waterlogging?
A)Enhanced clay mineral horizon elutriation✓
B)Accelerated chemical rock weathering rate
C)Increase in surface soil albedo
D)Atmospheric methane oxidation enhancement
💡 Explanation
Increased soil saturation from irrigation accelerates elutriation because it enhances leaching of clay minerals from upper horizons; therefore, horizon elutriation will be enhanced rather than weathering occurring uniformly without mineral differentiation or albedo being affected so drastically by water.
