Plume dispersion is about how an airborne release is moved and spread by the surrounding air. When a contaminant is released under pressure, it forms a plume that is carried away by wind and air currents, and its shape is influenced by turbulence and atmospheric conditions. This means the hazard travels downwind with the flow of air, possibly staying aloft or mixing with ambient air as it expands, rather than simply spreading along the ground or pooling due to gravity.

The other descriptions describe different behaviors: a conical pattern often relates to a strong energy release or jet that expands outward, not how a plume is transported by air; a pattern of liquid moving downhill is governed by gravity on the surface; and pooling in low-lying areas describes liquid accumulation rather than a vapor or gas cloud being dispersed through the air.
