Which dispersion pattern is described as low-lying liquid in an odd shape?

• A. Stream
• B. Hemispheric
• C. Pool
• D. Irregular

Answer: (C)

When a liquid spills and stays on the ground, the way it spreads depends on gravity, surface slope, and obstacles. A low-lying liquid that collects and spreads out into a shallow film forms a pool. The shape often looks odd or irregular because terrain features, edges, and debris influence how the liquid flows, pause, and pool in the available low spots. This pooling behavior—surface-level, shallow spread in a low area—fits the description of a pool pattern.

A stream describes a narrow line of liquid projecting from the source, not a broad, shallow surface layer. A hemispheric spread would form a dome-like shape expanding above the surface rather than pooling along the ground. An irregular pattern can occur, but it’s not specifically tied to a low-lying pool; pooling directly matches a liquid collecting in a surface film.
