magma i believe
Rock does not melt in calderas. It melts in the upper mantle.
A hot spot is a place where material from the magma melts through the crust in a non plate boundary location.
Calderas are very large volcanic craters. They are created when a volcano melts the land that it was formed around.
The crust is recycled by subduction which is.... a geological process in which one edge of a crustal plate is forced sideways and downward into the mantle below another plate
It is called a destructive plate boundry...one type of crust is oceanic and the other is continental. when they meet the oceanic crust gets pushed down as it is heavier. the friction caused when it sinks creates huge earthquakes and the crust re-melts and gets forced upwards due to pressure to form a volcano.

It is subducted toward the core and eventually melts, forming magma.

Subduction.
it creates a volcanoe

Heat from the mantle melts part of the lower crust.

mid-ocean ridge
it makes more magma.
