An area where a mantle plume forces magma through the crust that is not a result of plate boundary interactions is hotspot.
Answer: Option C
Explanation:
Magma refers to the name of the yellowish hot fluid before it comes out of the vent in the volcanoes, after it comes out of the vent it is termed as lava. Volcanic "hotspot" refers to a zone in the mantle from which warmth ascends as a warm crest from the core of the Earth. High warmth and lower weight at the base of the lithosphere (structural plate) encourages liquefying of the stone.
This soften called magma that ascends through splits and ejects to shape volcanoes. Thus it can be inferred that an area where a mantle plume forces magma through the crust that is not a result of plate boundary interactions is called a hotspot."
