A volcanic "hotspot" is an area in the mantle from which heat rises as a thermal plume from deep in the Earth.
Mantle Plume Debate
High heat and lower pressure at the base of the. A hot spot is a region deep within the Earth's mantle from which heat Instead it occurs at abnormally hot centers known as mantle plumes. While most volcanoes form along tectonic plate boundaries, mantle plumes and hot spots lead to their development as well.
Hot spot volcanoes.
By plotting the data on a graph and fitting the data with a line of best fit, the plate velocity can be estimated by taking the slope of the line. Rating is available when the video has been rented.

A third tectonic setting where volcanism occurs is called intraplate - or hot-spot -volcanism, which describes volcanic activity that occurs within tectonic plates and is generally NOT related to plate boundaries and plate movements.

Hotspot Lesson: Mantle Plumes This lesson explains a theory on magma This lesson defines hotspot volcanoes and the major contributors to the theory.
Such is the nature of science and why we continue to explore and learn. A mantle plume is an area under the rocky outer layer of Earth, called the crustwhere magma is hotter than surrounding magma.

As the tectonic plate moves over the stationary hot spot, the volcanoes are rafted away and new ones form in their place. Note the bulbous plume heads, the narrow plume tails, and the flattened plume heads as they impinge on the outer sphere representing the base of the lithosphere.
