Which dispersion pattern radiates away from a point source in all directions at the same time?

Which dispersion pattern radiates away from a point source in all directions at the same time?

• A. Hemispherical dispersion
• B. Cloud dispersion pattern
• C. Spherical dispersion
• D. Cone shape dispersion

Answer: (C)

When a release comes from a single point and expands uniformly in all directions, it forms a sphere. This spherical dispersion means the material radiates outward from the source in every direction at the same time, creating a growing ball around the release point. Real environments can distort this (wind, obstacles, buoyancy), but the core idea is a uniform spread in all directions from the point source. Hemispherical dispersion is limited by a boundary like the ground, cone shape dispersion channels the material into a narrow angle, and cloud dispersion describes a broader, wind-influenced cloud rather than a perfect sphere.
