← GeographyWhich effect increases when intense offshore trawling reduces seabed bioturbation?
A)Increased oxygen levels near sediment
B)Enhanced nutrient cycling in sediments
C)Stronger marine sediment stratification✓
D)Decreased suspended particle concentration
💡 Explanation
Stronger stratification will occur because bioturbation ordinarily mixes sediment layers; trawling decreases this mixing. Because mixing is suppressed, clearer layers form, rather than indistinct diffusion due to biological action normally.
