Which of the following occurs during a continental collision, after any subduction has ended?
A) the descending continental plate gets hotter and decreases in pressure
B) decreasing pressure causes downgoing crust to melt
C) volcanoes are widespread above continental collisions
D) all of these
E) none of these
Continental Collision
An event occurring when two continental plates converge, leading to mountain building, earthquakes, and other geologic phenomena.
Descending Plate
In plate tectonics, a slab of the Earth's lithosphere that is moving downward into the mantle at a convergent boundary.
Decreasing Pressure
A reduction in the force exerted by a fluid (gas or liquid) on a surface.

Final Answer :
E
Explanation :
During a continental collision, after any subduction has ended, the specific processes listed in options A, B, and C do not accurately describe what typically occurs. Instead, continental collisions are characterized by crustal thickening, mountain building, and deformation of the crust, rather than the scenarios described in the given choices.
