← GeographyWhich outcome occurs when intensified rainfall increases topsoil leaching?
A)Nutrient depletion increases stream eutrophication✓
B)Plant resilience from increased topsoil density
C)Enhanced soil carbon sequestration occurs then
D)Decreased subsoil aggregate stability develops slowly
💡 Explanation
Intensified rainfall causes nutrient depletion via leaching, where water carries away essential minerals and organic matter, because this runoff enriches water bodies downstream, leading to eutrophication. Therefore, (A) occurs rather than other scenarios, where soil composition is either unaffected or enhanced.
