Soil erosion:
A)may result in decreased water quality for fishes and other aquatic organisms.
B)does not reduce the fertility of the soil, just the quantity.
C)is exclusively linked to human activities.
D)is not affected by the extent of plant cover.

Question

Quizplus · Accepted Answer

Soil erosion can lead to increased sediment in water bodies, which can decrease water quality for aquatic organisms by reducing oxygen levels, blocking sunlight, or physically harming them. Choices B, C, and D are incorrect because soil erosion does reduce soil fertility by removing the top, nutrient-rich layer; it can be caused by both natural processes and human activities; and the extent of plant cover significantly affects erosion rates, with more cover generally leading to less erosion.
