What is the surface feature above a mantle plume called?

The surface feature above the mantle plume is known as the "hotspot".


What does an unconfined fire plume rises it becomes?

As an unconfined fire plume rises, it becomes less dense and cooler due to the dispersion of heat and gases into the surrounding air. This results in the plume transitioning from a narrow, concentrated column to a broader, more diffuse shape. The rising plume can also lead to the formation of smoke layers and turbulence in the atmosphere, which can affect air quality and visibility. Additionally, the plume's behavior can be influenced by environmental factors such as wind and temperature gradients.


What is a plume in hydrology?

In hydrology, a plume refers to a visible or measurable flow of one substance within another substance. For example, a plume of contaminant in groundwater refers to the movement of the contaminant within the groundwater. Plumes can be studied to track the movement of substances in water systems.


Is plume the same thing as a hotspot?

No, a plume and a hotspot are not the same thing. A plume is a column of hot rock that rises in the mantle, whereas a hotspot is a location on the Earth's surface where magma from the mantle comes up and creates a volcanic activity like a volcano. Hotspots can be associated with plumes, but they are not the same thing.


What is plume rise?

Plume rise refers to the vertical movement of a gas or aerosol cloud released into the atmosphere, influenced by factors such as temperature, wind speed, and atmospheric stability. Understanding plume rise is important in assessing the dispersion and environmental impact of pollutants emitted from sources like industrial stacks or wildfires.
