Sediment pollution sources?

Sediment pollution sources?

• A. Construction
• B. Agriculture
• C. Construction, Agriculture, and Deforestation
• D. Deforestation

Answer: (C)

Sediment pollution happens when soil particles are detached and carried into water bodies by rain or runoff. The main sources are activities that disturb soil or remove vegetation that protects it. Construction exposes bare soil and creates runoff paths, delivering substantial sediment to nearby streams. Agriculture contributes through tillage, overgrazing, and field runoff that wash soil into water. Deforestation removes the protective plant cover that stabilizes soil, increasing erosion and sediment delivery to waterways. Because all three activities contribute to sediment loads, listing construction, agriculture, and deforestation provides the most complete explanation of sediment pollution sources.
