hot spot- place of very high temperatures in the upper mantle that reaches the surface as a PLUME of extra ordinarily high heat.

The surface feature above the mantle plume is known as the "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.
The temperature of a volcanic plume can vary widely, typically ranging from around 200°C (392°F) to over 1,000°C (1,832°F) depending on the type of eruption and the materials involved. Volcanic plumes originate from the mantle or crust of the Earth, specifically from magma chambers beneath the surface. As magma rises to the surface, it releases gases and ash, forming the plume that can extend high into the atmosphere.
The surface location of a mantle plume is called a "hotspot." Hotspots are geologically active areas where magma from deep within the Earth's mantle rises to create volcanic activity, often resulting in the formation of volcanoes or volcanic islands. They can occur away from tectonic plate boundaries and are characterized by a relatively stable source of heat over geological time scales.
Hot Spot
Yes, a hotspot plume is believed to be located beneath Yellowstone National Park. This plume is responsible for the park's geothermal features, such as geysers and hot springs, due to the intense heat it generates. The Yellowstone Caldera, formed by volcanic activity associated with this plume, is one of the largest active volcanic systems in the world. The movement of the plume also contributes to the park's ongoing geological activity.
hot spot
Yes, Kilauea volcano in Hawaii is considered a hot spot volcano. This means it is formed by a mantle plume beneath the Earth's crust, creating a source of heat and molten rock that erupts to the surface.
of Plume
A hotspot volcano.
The Trojan plume refers to a specific geological feature observed on celestial bodies, particularly in the context of the Moon's surface. It describes a plume of gas and dust that can be ejected from the surface due to volcanic activity or impacts. In planetary science, the term is often associated with the study of lunar volcanism and the potential for such plumes to reveal information about the Moon's interior and geological history.
A plasma plume is a stream of hot, ionized gas that is ejected from a source, such as a spacecraft or a lightning bolt. These plumes can be found in various natural and artificial phenomena, and their behavior is of interest in fields like astrophysics and material science.
