What is the final result in the evolution of a continental hot spot?

The final result in the evolution of a continental hot spot typically involves the complete rifting of the continent. Hot spots are areas where plumes of hot mantle material rise to the surface, resulting in volcanic activity. As the hot spot continues to maintain its activity under a continental plate, it can lead to significant geological changes over time.

When a hot spot remains stationary while the tectonic plate above it moves, it can generate a series of volcanic features. In the long term, the heat and pressure can lead to extensive rifting of the continental crust. This process can create a series of fissures and faults as the crust thins and becomes more susceptible to breaking apart. If the rifting is extensive enough, it can ultimately result in the complete division of the continent.

Other options, such as the formation of curved island arcs, are more associated with oceanic plate interactions, particularly subduction zones. Rift arms being formed by faulting is a concept related to the initial stages of rifting, but the complete rifting implies a more final and thorough separation and alteration of the continental structure. Magma-filled fissures are related to volcanic activity but do not encompass the broader end result of continental rifting induced by a hot spot.
