What can a continental hot spot lead to?
A) formation of a curved continental outline along two rifts
B) localization of a river and delta along the failed arm of the rift
C) a thick accumulation of basalts and other volcanic rocks
D) a region that is high in elevation relative to adjacent parts of the continent
E) all of these
Continental Hot Spot
A volcanic region thought to be fed by underlying mantle that is anomalously hot compared with the surrounding mantle, situated in the interior of a continental plate.
Rifts
Linear zones where the Earth's crust and lithosphere are being pulled apart, often associated with volcanic activity and the formation of new oceanic crust.
Basalts
Dark, fine-grained volcanic rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron.
- Acquire knowledge of the concept and consequences of continental hot spots in the development of geological features.
- Comprehend the series of events that result in the genesis and progression of continental hot areas.

Final Answer :
E
Explanation :
A continental hot spot can lead to various geological features including the formation of a curved continental outline along two rifts, localization of a river and delta along the failed arm of the rift, a thick accumulation of basalts and other volcanic rocks, and a region that is high in elevation relative to adjacent parts of the continent. These phenomena are associated with the volcanic activity and tectonic processes occurring at hot spots.
