Which of the following activities is most likely to result in sediment pollution? a. cutting down trees b. pouring motor oil down the drain c. excess fertilizer use d. none of the above

Option:  A. cutting down trees

Explanation:

The cutting down of trees is most likely to result in sediment pollution. Sediment are soil particles, clay and loose sand which settles down in the bottom of the river or other water bodies. The reason for the loose soil is the soil erosion which happens when we cut trees. Sediment pollutes streams, lakes, rivers, and reservoirs. Sediment blocks passage of drains which crates water unable to flow and cause floods. Sediment also pollute water by creating it cloudy and preventing fishers and insects from seeing food.
