Most granitic batholiths are generated ________.
A)as intrusions beneath composite volcanos along convergent plate margins
B)where spreading ridges occur beneath continents
C)along transform faults,which accounts for their linear geographic distribution
D)along hot spot chains beneath continents,like a welder cutting through the continent to make a linear belt of intrusive granites

Question

Quizplus · Accepted Answer

Most granitic batholiths are formed through the intrusion of magma beneath composite volcanos along convergent plate margins, where subduction occurs. The magma is generated through partial melting of the subducting oceanic plate and rises to the Earth's surface, forming volcanos. However, if the magma cools and solidifies underground, it forms a batholith.
