Question

The increased concentration of suspended solids in water and their accumulation on bottoms where they are undesirable, creates what kind of water pollution?

• A. Siltation
• B. Microbiological pollution
• C. Nutrient pollution
• D. Thermal pollution

Answer 1

Answer:

A. Siltation

• Siltation refers to the process by which fine-grained sediments, primarily silt and clay, accumulate in a body of water, especially on the bottom.

• These suspended solids are typically eroded from the land surface due to factors like deforestation, agriculture, construction, and urban runoff.

• When these particles enter rivers, lakes, or reservoirs, their velocity decreases, causing them to settle out of the water column and form sediment layers.
