A plume is a feather-like structure often used to describe various natural formations or objects resembling feathers. In biology, it refers to the soft, elongated feathers of birds, typically used for display or insulation. In environmental science, a plume can also describe a visible, flowing mass of gas or liquid, such as smoke or oil, that spreads from a source. For instance, a smoke plume from a fire may extend into the sky. In geology, a mantle plume refers to a column of hot rock rising from deep within the Earth, contributing to volcanic activity.@Plume - RWA Chain #plume #plum
