← GeographyWhich change occurs during soil's pedogenesis from eolian deposition?
A)Humus accumulation at the soil surface✓
B)Increased grain size after long travel
C)Decreased chemical weathering rates immediately
D)Reduced porosity initially in the soil
💡 Explanation
Humus accumulation develops during pedogenesis because organic matter is added to mineral soil horizons via bioturbation, rather than coarser sediment sorting after deflation or decreased topsoil chemical availability; therefore it develops fertility.
