Which release pattern is described as a ball-shaped release of hazardous material?

Plume Release
Cone Release
Cloud Release
Hemispheric Release

The correct answer is: Cloud Release

The description of a ball-shaped release of hazardous material aligns with the concept of a cloud release. In a cloud release pattern, the hazardous material, upon being discharged, disperses into the atmosphere in a roughly spherical fashion. This occurs due to the buoyancy of the release, which creates a diffusion pattern that resembles a cloud as it spreads into the surrounding environment. The term "cloud release" often refers to gases or vapors that are released at high pressure and can form visible clouds that expand outward. Because they can be affected by environmental conditions like wind and temperature, they can travel significant distances from the point of release, posing potential risks to areas beyond the initial discharge site. The other release patterns mentioned typically have distinctive shapes and mechanisms that do not fit the description of a ball-shaped dispersion of materials.
