Answer and Explanation: Intraplate volcanoes are caused by hot spots inside a tectonic plate and far from the edges. Intraplate volcanoes happen in particularly hot areas of the mantle called mantle plumes.

How does most intraplate volcanism occur?
The majority of active terrestrial volcanoes (roughly 80 percent) and related phenomena occur where two tectonic plates converge and one overrides the other, forcing it down into the mantle to be reabsorbed. Long curved chains of islands known as island arcs form at such subduction zones.
What causes intraplate volcanism formation?
Plumes are postulated to rise through the mantle and begin to partially melt on reaching shallow depths in the asthenosphere by decompression melting. This would create large volumes of magma. The plume hypothesis postulates that this melt rises to the surface and erupts to form "hot spots".
Where does intraplate volcanism occur?
Intraplate volcanism is volcanism that takes place away from the margins of tectonic plates. Most volcanic activity takes place on plate margins, and there is broad consensus among geologists that this activity is explained well by the theory of plate tectonics.

hotspots.
What causes intraplate volcanism quizlet?
What causes intraplate volcanism? Intraplate volcanism is caused by hot mantle plumes rising up from the coremantle boundary, causing decompression melting and forming small areas of volcanic activity on the surface.
Which volcano is an example of intraplate volcanism?
The most remarkable example of this is the Emperor chain, the older part of the Hawaii system, which was formed by migration of volcanic activity across a geo-stationary plate.

Where does most intraplate volcanoes occur?
Activity within a plate is called intraplate activity. Most intraplate activity occurs at hotspots. Hotspot volcanoes erupt mostly on oceanic crust.
What are intraplate volcanoes called?
Although most volcanic rocks are generated at plate boundaries, there are a few exceptionally active sites of volcanism within the plate interiors. These intraplate regions of voluminous volcanism are called hotspots.

How are intraplate volcanoes formed and what is an example?
A relatively small number of volcanoes occur within plates far from their margins. Some, as exemplified by the volcanic islands of Hawaii that lie in the interior of the Pacific Plate, are thought to occur because of plate movement over a “hot spot” from which magmas can penetrate to the surface.
