← GeographyWhich consequence resultes from decreased porosity inhibiting pedogenesis?
A)Accelerated mineral translocation to B-horizons
B)Diminished organic matter decomposition rate✓
C)Increased leaching of mobile elements
D)Enhanced eluviation within the topsoil
💡 Explanation
Decreased porosity slows oxygen and water movement, reducing microbial activity rates responsible for organic matter decay. This reduced microbial transformation hinders pedogenesis because decomposed organic acids enhance profile development, rather than mineral movement.
