Final answer:
A dome-shaped dispersion pattern in which some material stays on the surface, but the rest becomes airborne is known as a Plume.
Step-by-step explanation:
The dome-shaped dispersion pattern in which some material stays on the surface, but the rest becomes airborne is known as a Plume.
One example of a plume is volcanic ash. When a volcano erupts, the ash is initially dense and falls near the source, but as it rises, it spreads out and becomes airborne, forming a dome-shaped plume.
Another example is a smoke plume. When a fire burns, the smoke initially rises vertically, but it can spread out horizontally forming a dome-shaped plume. The particles in the plume can stay in the air or settle back to the ground depending on various factors.
