Final answer:
Hot spot related seamount formation occurs when tectonic plates move over stationary hotspots of heat from the mantle, resulting in volcanic activity and the formation of seamounts.
Step-by-step explanation:
Hot spot related seamount formation occurs when tectonic plates move over stationary hotspots of heat from the mantle.
Hotspots allow hot mantle material to rise close to the surface, resulting in volcanic activity. If hotspots occur under oceanic crust, they produce basalts, while under continental crust, they form both basalts and rhyolites. As plates move over hotspots, volcanic activity forms seamounts.
