Which of the following is a dispersion pattern for liquid holding containers?

• A. Streams
• B. Pools
• C. Clouds
• D. Rivers

Answer: (A)

Dispersal of a liquid spill across terrain follows gravity and the surface it’s on, and the typical pattern is a stream. When a liquid leaks from a container, it will usually flow downslope, forming a narrow, continuous channel that can transport material toward drains, low spots, or nearby waterways. This stream pattern is how you predict where the contamination will travel and which areas are at risk. A cloud describes vapor dispersion, not a surface movement of liquid. A river is a natural watercourse, not the immediate dispersion channel produced by a spill. Pools can form in flat areas or depressions, but they’re static and depend on terrain; the common initial dispersion from a leaking liquid holding container is a stream.
