Which term describes the dispersion pattern where liquid collects in low-lying areas?

• A. Stream pattern
• B. Plume pattern
• C. Pool pattern
• D. Cone pattern

Answer: (C)

Liquids on ground surfaces tend to settle into the lowest spots, so they can accumulate and form a relatively still body in depressions or low-lying areas. This accumulation is what we call a pool pattern—the liquid pools in those low spots rather than flowing in a channel or dispersing into the air. The other patterns describe different behaviors: a stream pattern would be a continuous flow along a path or channel, a plume pattern involves spreading through air or across the surface in an elongated, dispersed form, and a cone pattern describes a spreading, outward shape from a source. Pool pattern specifically captures the idea of liquid collecting in low areas.
