← GeographyWhich process diminishes topsoil horizon thickness following deforestation?
A)Accelerated erosion of unconsolidated material✓
B)Increased rate of mineral weathering
C)Enhanced organic matter decomposition
D)Reduced bioturbation by soil fauna
💡 Explanation
Deforestation removes vegetative cover, greatly increasing erosion due to rainfall impact, therefore unconsolidated material is easily washed away rather than furthering soil formation by pedogenesis, because interception is reduced and surface runoff is drastically increased.
