Which process diminishes topsoil horizon thickness following deforestation?

💡 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.

• On valley flanks in mountainous areas, which erosional outcome results from intense freeze-thaw cycles?
• Which seismic phenomenon typically results along a transform plate boundary undergoing strike-slip faulting?
• Which consequence results when persistent winds cause deflation in arid landscapes underlain by varied sediment grain sizes?
• Which outcome develops when sediment supply exceeds transport capacity on a rapidly subsiding basin with proximal mountain uplift forming a braided stream?
• Which weathering process creates exfoliation domes in granite?
• Which process limits the lifespan of oxbow lakes formed by meandering rivers in floodplains?
