Question

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

please select the best answer from the choices provided

a
b
c
d

Explanation:

• Option a: Cutting down trees (deforestation) removes vegetation that holds soil in place. Without tree roots and ground cover, soil is more easily eroded by wind or water, leading to sediment (eroded soil particles) being carried into water bodies, causing sediment pollution.
• Option b: Pouring motor oil down the drain causes chemical pollution (oil pollution) of water, not sediment pollution.
• Option c: Excess fertilizer use leads to nutrient pollution (eutrophication) when fertilizers run off into water, not sediment pollution.
• Option d: Is incorrect because option a does cause sediment pollution.

Answer:

A. cutting down trees
