Deep slow-moving water with more sediment is called which feature?

• A. Pool
• B. Infiltration
• C. Runoff
• D. Riparian Zone

Answer: (A)

Pools are the deep, slow-moving parts of a stream where the water velocity drops enough for suspended sediments to settle to the bottom. That slower flow lets particles deposit, building up sediment on the bed and creating a deeper, calmer habitat compared with faster, riffling sections. In contrast, infiltration is water seeping into the soil, runoff is water flowing over land into a water body, and the riparian zone is the vegetation-rich area along the banks—none of these describe a water feature inside the stream itself.
