Which pattern describes a liquid pattern where movement is down slope due to gravity (drains to lower areas)?

Which pattern describes a liquid pattern where movement is down slope due to gravity (drains to lower areas)?

• A. Pool pattern
• B. Spherical dispersion
• C. Plume dispersion
• D. Stream dispersion

Answer: (D)

When a liquid on a surface is pulled by gravity down a slope, it tends to form a narrow, continuous path that follows the terrain toward lower elevations. This creates a stream-like pattern as the liquid channels downhill and drains toward the lower area, hence stream dispersion. Pool dispersion would mean the liquid pools in a low spot and doesn’t move downslope as a flow. Spherical dispersion implies the liquid spreads outward evenly in all directions from a single point, not along a downhill path. Plume dispersion describes a directional spread from a source, often influenced by wind or flow through another medium, rather than a gravity-driven downslope channel on the ground. So, the pattern described—movement down slope toward lower areas—is best captured by stream dispersion.
